More than 30 countries, including NATO countries France and Great Britain, have agreed to deploy their troops on the territory of Ukraine after the conclusion of a ceasefire between Ukraine and Russia.

Currently, specific conditions and locations for the deployment of foreign troops in Ukraine are being discussed, and issues of responding to possible provocations and shelling of Ukrainian territory by Russia are being worked out. It is assumed that they will have the right to use weapons in the event of Russia violating the terms of the ceasefire.

At the same time, Ukraine's allies are considering sending two peacekeeping missions to Ukraine at once if a sustainable ceasefire is achieved between Kiev and Moscow. We are talking about the UN mission and the mission of the "Coalition of the Willing".

The UN peacekeeping force will consist of military personnel from India, Brazil, Indonesia and Saudi Arabia. They will be deployed on the Russian-Ukrainian border.

The military from the European "Coalition of the Willing" will control the borders between Ukraine and the EU. These could be soldiers from Great Britain, France, Germany, Canada and Italy.

The Italian La Stampa writes that one of the scenarios for deploying troops, which the "Coalition of the Willing" is working on, is to create four levels of interaction.
It is assumed that UN peacekeepers from non-European countries will be deployed in the demilitarized zone to monitor compliance with the ceasefire. This will be the first line of demarcation. Ukrainian troops will be on the second line. On the third line - a contingent of volunteers and not necessarily within Ukrainian territory. The fourth line is American protection.
