I'll repeat it again. There was no reasonable threat by Ukraine to Russia. None! Ukraine was NOT seeking to become a member of NATO although they have every right to do it. Ukraine was not a threat to invade Russia.
There is no justification for what Russia is doing. None!
If that’s the case WHY did Putt King help overthrow their government???
Just remember there were/are very many Pro-Russians in Ukraine as well !!!
You can repeat it until the cows come home, but that still won't make it true. Of course Ukraine is "not a threat to invade Russia" but its possible alliance with NATO would pose an unacceptable threat to Russia's defense in the event of war against NATO. Great powers -- the USA and Russia included -- don't quibble over right and wrong in matters of their strategic defense, and bordering countries either cooperate or get stepped on. That isn't fair, it isn't nice and it isn't pretty, but that's just the way it is.
Just consider the Monroe Doctrine that the United States has rigidly enforced since 1823... It has been our policy that any intervention by outside powers in the politics of the Americas is considered a hostile act against the United States itself. The doctrine was expanded at the turn of the 20th Century to justify US intervention throughout Latin America as we saw fit. Was there any justification for that? How much differently is Putin behaving in Ukraine today than Presidents Monroe, Tyler, Polk, Johnson, Cleveland, TRoosevelt and Kennedy did when they threatened or actually enforced the Monroe Doctrine throughout our hemisphere? Not a single one of these examples is pretty to look at, but asserting strategic self interest is what great powers do or else they die.
