EN
Israel since the beginning of its existence struggles with exterior and interior threats connected with national security. For over twenty years terrorist attacks have intensified. In order to fight against this phenomenon, it was necessary to create an anti-terrorist system. The author describes the role of Israeli army in the anti-terrorist system created in this country. He points at the ways to perform tasks assigned to the armed forces in the area. He gives examples of anti-terrorist operations carried out by Israeli military special units, including the most famous one, connected with the raid on Uganda’s territory in order to set free Israelites, passengers of a plane hijacked to Uganda by Palestinian terrorists. The author presents in the article aims that the Israeli authorities want to achieve engaging the armed forces in land, maritime and air actions against terrorist organisations and he also provides examples of penalty sanctions (executed both in Israel and in occupied territories as well) against terrorist groups members or supporters.

The content of the article refers to units functioning in Israel and assigned to physical fighting against terrorism. This country has undoubtedly the greatest experience to fight this phenomenon and its knowledge is used by many countries. In the introduction the author discusses the genesis of appearing and transformation the General Staff Intelligence Unit, Sayeret Mat’kal from a military special unit into anti- terrorist unit. From the article it results a relation between the service in this exclusive unit and the participation in the Israeli political life. There are given examples of this country’s in leading political world representatives careers, Prime Minister, Benjamin Netanyahu including, whose career started in serving in this unit. The rest of the article concerns police anti-terrorist unit, YAMAM. The author presents a historical outline of this unit creation, existing in border police, main tasks for which it was established, the recruitment system for the candidates to this service. Some aspects of specialistic training have been touched on, particularly in the basic training context of this service candidates. Basic combat means of police assault units and transport means with the stress on reconnaissance vehicle equipment have been discussed. The author described the unit’s ways to achieve their own tactical solutions on the example of the team of pyrotechnists functioning in the unit dealing with using explosives to overcome such obstacles as walls, bars, closed doors and in this context conducting actions connected with rescuing hostages. The author has focused on these aspects and these solutions appearing in YAMAM which are different from our Polish ones and, at the same time, are worth paying attention and adaptation in our conditions. The content of the article is the result of the author’s visit in an Israeli anti-terrorist police unit.

Terrorists attacks of September 11, 2001 caused a new approach towards the problem of terrorism and fighting against it. The attack of international terrorism onto New York and Washington was called a war that was waged against the whole free world. The author points out in the article to these factors that allow proving this thesis. He discusses probable effects of such attacks on the stability of power in a state. He refers to the sources of terrorism presented by Islamic fundamentalists and shows that the September 11 events were planned and purposely arranged to engage the United States in war which it would supposedly lose. The probability to continue attacks by terrorist organisations using mass destruction weapons has been mentioned in the article. In the conclusion the author points out to the need of constant necessity to counteract and fight against terrorism and, in particular, to create rational solutions for effective fight against terrorism in Poland.

In the article the author defines the notion of antiterrorist tactics, which is based on war art principles in a tactical dimension characteristic for land forces. The author enlarges the principles binding in Polish armed forces by two additional ones: “simplicity” and ’’one - man command”, which are mentioned in American sources. Basing on them, the author discusses variables connected with tactic principles belonging to antiterrorist tactics. They include “planning and exercise”, “speed” and “security”. In the second part of the article the author presents American viewpoints on a very important issue which is a model mental state of an antiterrorist subunit soldier and demanded level of this unit soldier’s mental activity on different level of his activity.

The article relates to using special forces to fight terrorism. It is one of the forms to use by the state military special forces to fight against non-military threats. Constantly growing threat of terrorism in the world causes the need to use these forces soldiers' skills to conduct operations aiming at freeing hostages. The author describes one such actions, carried out in the second half of the 90s by Peruvian special in the capital, Lima. This daring operation using the element of surprise, which was to dig an underground passage under the building, earned respect of anti-terrorist specialists in the world. The course of attack, the planning process and its preparation have been described in the article on the background of the situation development in the occupled building. This successful rescue operation proved how effective special forces can be in counter-terrorist operations.

The author refers to Israeli - Palestinian peace process and the threats coming from terrorist organisation Hamas. He presents his viewpoint on the issue to decrease to minimum terrorist groups’ activities in Israel through normalisation of relations with this country’s Arab neighbours. He describes in detail Israeli soldier’s, Corp Waxman’s, abduction and killing and also Israeli special forces’ rescue action aiming at rescuing from terrorists’ hands. This event is discussed in the aspect of its impact on peace talks. Giving examples of terrorist attacks that took place in Israel in 1994 - 1997, the author points out how difficult the road is to normalise peacefully the Arab - Israeli conflict in the Middle East where fanatic terrorist organisations are ready to provoke even a military conflict in this region instead of a constructive dialogue.

After the communist block collapse, other than military threats for the functioning of the state were noticed. The security understood at that time only in war and peace categories lost its meaning in the new reality. New unfavourable phenomena were discovered, the escalation of which may lead to destabilisation of the state structures or even, in consequence, to an open military conflict. Terrorism and organised crime are included in these threats category. Terrorism is not a phenomenon that in Poland poses a great threat towards security, however, organised crime is included in these categories. The article deals with terrorism, its evolution in the last thirty years and also with organised crime that in some cases may appear as a mafia organisation. The author describes the mentioned above threats, relating to their most crucial elements and also a real possibility of their existence in Poland. He also shows how the Polish authorities are prepared to counteract and fight them.

Terrorism is currently considered the most important source of threat to the security of the state. The problem of counteracting and combating terrorist threats is a focal point of attention for services responsible for the security of the state. There emerge short and long-term plans in order to postpone or limit the possibility of terrorists’ effective actions. In countries that have encountered terrorism for many years, Western Europe in particular, appropriate preparations to this type of threat are considered very seriously. France’s approach, where the plan “Vigipirate” has been functioning for years, can serve as an example. It assumes using all assets and forces (armed forces including) to ensure antiterrorist security of the state. Also the Czech Republic developed and implemented "National Plan of Actions to Combat Terrorism” after September 11. In Poland, in spite of the authorities' declarations concerning terrorist threat awareness, no particular steps have been taken to organise and co-ordinate all bodies that would have an essential influence on antiterrorist security. There still functions the ministerial approach to the problem of counteracting and combating terrorist threats. The author suggests one of possible solutions, the implementation of which would change the current state of affairs.

Contemporary terrorism is all the time looking for new assets to carry out a spectacular attack. Terrorists’ aim is to shock everyone in the world. One of the “ways” of searching for new methods to conduct attacks by terrorists is turning to weapons of mass destruction. The article refers to factors and possibilities to use a dirty bomb, Radiological Dispersion Device (RDD) in terrorist attacks. The author describes exercises that were held by the Spanish authorities in October 2008 preparing to a situation when such a weapon might be used. It is shown what actions should be taken in the area of anti-terrorism in order to increase Poland’s security level.

The author discusses the issue of terrorist actions conducted by Islamic fighters against Israel. He presents the picture of the region suffering from wars and Israeli - Arab conflicts. He points at increasing influence of religion - Islam on the shape and scope of present terrorist actions aimed at Israel as an enemy in their jihad - a holy war fought by Muslims. The author is of an opinion that the activity of terrorist religious groups is connected with abandoning this kind of actions by Palestinian secular groups engaged in the peace process in the Middle East. He presents the scale of Islamic terrorist groups activities in the world and gives example of terrorists attacks on Israeli citizens and objects in different parts of the world. He discusses examples of prevention actions and shows the danger that results from the attacks of the possibility to provoke a military conflict or war in the Middle East.
