In 2014, Russia annexed part of Ukraine under the guise of militias and rebels. Later, Putin openly admitted that these were regular military personnel and that it was a well-planned operation (the deception). He was proud of it.
In late 2021 and early 2022, Russian media and Putin personally assured that they were not going to attack Ukraine. Until February 22, 2022, missiles flew at us, and convoys of Russian military equipment, supported by aviation, moved across the Ukrainian border.
All this time, Russians have been killing and torturing Ukrainians just because they don't want to give up their identity. In front of the whole world.
In the fall of 2022, Russia added 4 Ukrainian regions to its constitution as Russian. These regions were not then and are not now under the full control of the occupation forces. Once again. Russia unilaterally added part of another sovereign country to its constitution. And now it is trying to make these areas a subject of bargaining.
This is everything you need to know about international agreements and security guarantees in the 21st century.
I don't care who else says that Ukraine attacked Russia - Putin, Lavrov or Trump. This is not true. There are facts that cannot be interpreted otherwise. And yes, presidents can be liars.
