The idea that wars are evil, and it is necessary to maintain order by all means and prevent armed clashes, has been visiting various representatives of the human race since ancient times. Attempts to create a collective security system in Europe began in the 19th century.
What is a collective security system?
The collective security system is a joint action of all the states included in it, aimed at supporting world peace, as well as suppressing aggression. This system includes several components.
Firstly, it is based on generally accepted principles of international law, of which the most important are the allegations that the borders and territorial integrity of all states are inviolable, and that one cannot interfere in other people's internal affairs, especially by using force.
Secondly, these are collective measures from all states included in the system, directed against acts of aggression and threats to peace. Thirdly, these are disarmament measures, and ideally, bringing all states to complete disarmament.
Collective security systems have the right to carry out armed actions aimed at pacifying aggression.
