As a resident of Ukraine, I will explain the situation. The start of this process began in 2014, when mass demonstrations began in Ukraine against the rotten power of President V. Yanukovych. Reason: in 2013-2014, the key goals of the country for the nearest period were agreed and spelled out, namely the European vector, integration into the economic and political processes of Europe and Western ideas and values. The key idea was to avoid any binding and imposed alliances with Russia. For some reason, Russia believes that all neighboring countries are OBLIGED to enter into an alliance with it, to become a supplier of cheap resources and a buyer of its low-quality products. Alliances with the Russian Federation have never been mutually beneficial. Well, many decades of occupation, and the mass destruction of Ukrainian citizens by Russia / USSR also influenced the choice of Ukrainians. But without the resources and potential of Ukraine, Russia is very uncomfortable. And the worst thing for Russia is an example of the fact that a country from its inner circle can show an example of how you can drive out a president a thief and a criminal, and start free changes to improve life! By the way - at the moment, despite the fact that both direct hostilities from Russia and terrorist actions are taking place against Ukraine, the level of the Ukrainian economy is growing, and in 2021, the minimum income level exceeded the same level in Russia, the richest country world
And the tales about Putin worrying about the security of Russia are a bluff for his sheep
At the same time, he himself constantly, and all propaganda channels, tell how powerless NATO is, backward, lazy and cowardly, and a huge number of super-weapons have been invented in Russia, which will destroy in seconds any enemy, his missiles, tanks, ships, aircraft. You cannot imagine how much money Russia is investing in propaganda channels that carry these crazy tales to the masses!
Well, to the main topic - if Russia manages to capture Ukraine, although we will definitely resist this, Russia will not stop there. They openly declare that they want to create a new empire, and forcibly annex ALL the territories that were in the USSR - that is, ... return back to Ukraine, Moldova, Latvia, Lithuania, Estonia, punish Poland for its desire to live well, establish its own rules for Europe, monopolize the gas market in the EU. Do not be lazy - listen / read state official propaganda channels such as RT, ORT and the like, you will hear a lot of interesting things both about yourself and about the whole world, where "kind and decent Russia" is, and the rest of the world is angry with her
Therefore, sanctions, including disconnection from SWIFT, are a deterrent mechanism to prevent the spread of RASHISM (Russian fascism) around the world.
