"at the very beginning of their strategy"
easier said than done. eg: Afghanistan. After 9/11, the US hit the Taliban fast and hard, "un-measured", but the Taliban and jihadis are still running around and killing US + allies in Afghanistan 4 years later. Iran is untouched, Syria is untouched, and both are supporting the Iraqi insurgency. dubya talks tough about countries harboring/supporting terrorists, but he does nothing about them. He's a cheap-talk, loose-lips bull ting faker.
And just who, where was the US supposed to hit "un-measuredly" in the days after the Cole attack? Massacre a bunch of dancing Yemenis? Were they they actual terrorists?
Macho Man Reagan turned and ran after the Marine barracks blast in Lebanon.
Who, where was he supposed to hit?
Clinton didn't respond to Khobar Towers attack.
Who, where was he supposed to hit?
That's why Genest is an academic instead of a combat commander.
