In the case of Korea and Afghanistan, the US or US forces were attacked. In Vietnam we were asked in by the local government being attacked by a Soviet ally. In Iraq we were stuck patrolling and enforcing sanctions under a UN mandate even while our forces were shot at. With the exception of Panama, in Latin America we intervened without invasions or very limited forces to prevent Soviet allies from taking power.
In no case did we annex territory.
It's been a bedrock policy of the US after the WWII territorial changes that we stop powers from annexing territory or making territorial claims backed by threat of force because that kind of great power rivalry led to both world wars.
How’s that policy working out for America? How many wars has it actually won post WWII? American policy in this case isn’t trying to stop a world war, it’s determined to start a world war. So is Russian policy. These two idiots are going to get us all killed.
Stop crowing about Ukraine and negotiate a settlement. Give the Russkies eastern Ukraine and let it go already. Stop with the color revolutions and keep Ukraine strong enough to balance out Russia.
AVOID NUCLEAR WAR. At all costs. Get the gas flowing again. End sanctions, get the world economy on track. We need to be fighting the WEF and economic destruction not on distraction in Ukraine. You understand that Western policy is simply a distraction from government dismantling the economy right ? Ukraine is a side show. a non issue in the great scheme of things
