> Is it physically possible to detect imminent attack

Yes. Air defense does this pretty consistently.

And then what? We (Ukrainians) have lost some components of the PATRIOT air defense system because we were out of interceptors. Imagine being an air defender on duty on the best hardware in the world, facing the missile incoming and being incapable of doing shit because you're empty because of... democracy. The very thing being protected right now from that specific missile.
