The only weapons the US won't send are ones that can hit Russia proper. Who cares if a HIMARS missile is reverse engineered, Russia's GPS equivalent barely works. It's so bad that their pilots are using commercial GPS equipment instead of their equivalent. And what do you mean detect and counter US missiles? They've had radar for decades, they've always been able to see them. The issue is a matter of the quantity of the HIMARS missiles coming down, and a lack of time to shoot them down because again, they are missiles.
