The US has wasted over 350 billion dollars on this with nothing to show for it. And that's an attempt to stop one ICBM with one reentry vehicle.
Russian missiles are far more sophisticated and their launchers are all over the place. You can't stop them on the ascent phase where this would be feasible.
After that stopping a modern ICBM is impossible. A single missile contains up to a dozen warheads (MIRV) plus decoys all moving at several miles per second! There's no hope.
No amount of wishful thinking is going to overcome basic physics.
If we don't like the dictator we should depose them and support democracy everywhere. Instead we worked with Putin, we helped install him, Europe helped legitimize him. It's on us that we're in mortal danger again.
