The power requirement is a challenge, but taking out decoys is doable. Warheads are built to withstand the heat of re-entry. But we already have the technology to do the job; it just needs to get into space. I am guessing that some of it is already up there thanks to Elon. If they did what I suggested several years ago, then we are in good shape. As far as Europe goes, maybe we can get them to buy THAAD-ER from the US.
