So what about the fact that

1. the democtraticly elected government of the Ukraine is deciding to continue or surrender. Military aid is not forcing them to fight but helping then after they have decided to do so.
2. There is little stopping Russia from attacking other regions or contries after they overtook the eastern part of Ukraine. They allready stated they see Poland and Moldova as part of the "russian world" they want to create

I do agree that there were breaches of verbal agreements by the NATO but there is rarely a more clear aggresor than when one contry invades an other. You may now start with whataboutism, the us and all the countries they invaded but two wrongs don't make a right
