What is the alternative then?

Nobody has done anything after the fake bombings before the Cechnya intervention in 1999, which at least is in their own territory. But then again silence in 2008 after the Georgia invasion, and again in Crimea in 2014. They are using their nuclear arsenal as a free pass to invade everyone and break every treaty.

I think it just became unsustainable at this point. And honestly this is the best we can do to help without making things worse.
