Totally agree. We have (essentially) all of the military might, start putting up defense shield, then invade the wrong country, against the better intelligence of the Russians and some Europeans. I also sympathize a bit with the Russians for wanting their own checks and balances against the US, as our attitude was clearly "we're going to do whatever we want and don't really care what you think."
Perhaps surprisingly, but I also agree with the situation from Russia's perspective.
There's an argument to be made about ABM against small-state actors like Iran and NK, but any system that becomes a serious deterrent to ballistic missiles puts an incredible upheaval in our "balance of power" and potentially leads to an arms race, increase in conflict, proxy wars, etc. Not good news.
I don't agree that Russia should have a say in when NATO would be able to operate such a system, but a notification requirement would be fine, if not actually allowing a Russian liaison to be stationed with the operations center controlling such a system.
