In 6 months or less. Just as they forgot about Afghanistan. Perhaps a little longer because it's on Europe's doorstep. Americans have a very short attention span. A lot of flag waving from individuals who could not point to Ukraine on a map. And no we should not enforce a no fly zone. I think banning Russia from swift is a serious error and the dollar's dominance will continue to be chipped away. American power is on the decline and we are moving to a multipolar world. With each additional sanction on Iran, Russia, etc they slowly lose their effectiveness as these countries will begin to operate completely in their own bubble. Be careful what what sow.
