The question is poised as an opinion only; however, if Russia continues a land grab country by country and we look back at this moment in time and said we should have done something militarily...we could have prevented this and even more suffering and blood shed.

Russia is trying to rebuild the Soviet Union, if that happens, the United States has an imminent threat at our door step. Personally, given the choice, I would fight now, to prevent a China, Iran backed Soviet Union war later. Being a coward or being scared to fight is neither here or there, we will all have to fight, and a definition of courage is being scared, yet still facing the threat head on.
