Ignorance. It is not about whose missiles they are.
If Poland and Romania have security concerns, being former slave states of Russia/Soviet Union, it is their prerogative if they choose to have military assistance from anyone. If Russia wants to claim it is an “American” threat, while ignoring its missiles and other military are considered a security threat to some in Eastern Europe, and you want to swallow that propaganda, go ahead.
You are buying Blinken’s denial, where he is trying to talk hair when the head is at stake.
Russia is obviously not going to nuke Europe because her defense doctrine is based on MAD, Europe is not a side to, not counting the American strategic infrastructure there. Poland is not capable to threaten Russia on her own.
It is the essence of Putin’s ultimatum. He is essentially threatening CONUS, but Blinken is playing idiot and trying to downplay it into the Ukrainian issue.
It was, is, and always will be about the strategic balance between the US and Russia. Everything else is irrelevant and a distraction.
On your part, maybe.
It is not in the national interest to have corrupt Eastern European countries dictating the defense posture of the United States.
