Those won't shoot down ICBM re-entry vehicles with any degree of reliability, no matter where we put them. They might enable us to win a ground war, but then he just nukes the snot out of us, so we're not doing that.The only missile systems the US has forward deployed in Eastern Europe are Patriot PAC-3, THAAD, and Aegis ashore, all of which are defensive anti-ballistic missile systems.
The reason Putin went screwy is that these defensive missile systems have the capability to mitigate or negate Russia’s nuclear first-strike capability.
I don't think Putin is worried about his first strike capability. I think he's worried about our ability to generate a credible, disabling one. If that happens, he's at our mercy, and he won't tolerate that. So, when we removed Yanukovych, he took steps.
I don't think the invasion was strictly speaking necessary given that we're very unlikely to admit a country to NATO that is actively at war with Russia, which Ukraine already was. I'm also not privy to the conversations inside the Beltway, so it's possible he has better information about that than I do.
I think he simply thought that he would win relatively quickly (most of us did), put a longstanding set of territorial disputes to bed and gain a little breathing space with respect to the nuclear defense problem. That turned out not to be accurate.
