Not sure what you are talking about. The last I looked we still have Aegis Ashore "dual purpose" cruise missile systems stationed in Romania and Poland. This most certainly does NOT make Putin "happy". Here is what he said at a speech to his Defence Ministry Board in 2021:

"It is extremely alarming that elements of the US global defence system are being deployed near Russia. The Mk 41 launchers, which are located in Romania and are to be deployed in Poland, are adapted for launching the Tomahawk strike missiles. If this infrastructure continues to move forward, and if US and NATO missile systems are deployed in Ukraine, their flight time to Moscow will be only 7–10 minutes, or even five minutes for hypersonic systems. This is a huge challenge for us, for our security."

As far as Fiona Hill is concerned, I am not a fan. She is a Putin-hating spook who spent many years at the ODNI and even worked under that evil monster Negroponte when he was DNI. She is a Neocon of the highest order. Her time at the Brookings Institution also makes her suspect, and only further burnished her Neocon credentials. I think she was a stealth appointment under Trump and was there to sabotage any fledgling detente that Trump might have wanted to pursue with Russia. Certainly the fat that Trump didn't even recognise her the first time she was in his office would indicate that.
