It takes 30-40 minutes for an NK icbm to reach the US. About 20 minutes to guam. But the US missile defense has never seen combat.. only tests. They had 10 successful tests (the last 10) out of 18. But those are planned ahead of time (with trajectories already mapped out), and the missiles don't have countermeasures (which they would in a real conflict). So there's a big question about whether the system will work at all. I don't think anyone is eager to find out. https://www.reuters.com/article/us-northkorea-missiles-usa-defense/lack-of-real-world-testing-raises-doubts-on-u-s-missile-defenses-idUSKBN1AP2R3 https://www.reuters.com/article/us-northkorea-missiles-usa-d...
