is Ukraine a warning to every other country that borders Russia that wants to become pro-western?

[Lost Equation]

Ukraine is split in half. Part of the country wants to join the European Union (EU) and the other part is pro Russia. Ukraine borders with seven countries: Poland, Slovakia, Hungary, Romania, Moldova, Russia, and Belarus. Four of the countries that border Ukraine belong to the EU (Poland, Slovakia, Hungary and Romania).
There is no way that Putin would try and attempt to take over those countries...not that he wouldn't want take control of all of europe, but it will never happen.
Putin wants as much territory as possible. Ukraine is weak military and he knows it. He does not want them to become part of the EU.
Time is going to tell what the outcome will be because Ukraine has a dvidided ideology .
