The principle of 'National Sovereignty' should be foremost...but of course Obama, Congress, no longer consider what the people think....nor the Constitution reads...they're no longer abiding by it or any rules but making their own as they go
Just imagine the conversation:
(Phone rings)
Putin: Hello?
Obama: “It’s me again President Putin. I demand you remove your troops from Crimea.”
Putin: “President Obama, remove your military base from Guantanamo in Cuba.”
Obama: “What happens in the Western Hemisphere stays in the Western Hemisphere. It’s none of your business.”
Putin: “What happens in the Eastern Hemisphere stays in the Eastern Hemisphere. It’s none of your business.”
Obama: “But France and Germany say ...”
Putin: “France, Germany, pfft. With Germany we’d been there, done that, remember 1941-45? Is momma Merkel sure to go there again?”
Obama: “Well, I draw the red line, too bad you ignore it.”
Putin: “Oh, no, red lines, and more red lines, what are you, a communist? Ha!” (Click.)
