US military is powerful enough to crush enemies, but can it defeat their 'final 10%?'

The US military's power is being tested in conflicts such as the Russia-Ukraine war and the Iran wars, where new technologies like unmanned systems and precision strikes are changing the nature of warfare. The Russia-Ukraine war has resulted in significant casualties and a relatively stable front line. The Iran wars have demonstrated the use of drone swarms and ballistic missiles, posing challenges to US air defenses.
