Okay, you vastly overestimate the jihadist capabilities at conventional warfare. They don't have nearly the ability of the Americans let alone the west. Even though american power is waning, she can still throw massive industrial power into any conflict that properly motivates her people. Now industrial power is one of the major keys to wining a conventional war. Its how the allies beat the Germans with inferior guns and tanks, despite the Germans fielding brilliant tacticians and achieving what was thought to be impossible in mere months. The simple truth was american could built 50 m4 Sherman's for every tiger tank. Now these jihadists do not close the industrial power of pre ww2 Germany or they're fucking legendary engineering and tactical abilities. Give america a Bogey man like jihadist and she is weak because she is unlike other past powers in her shear brutality ( not to say they haven't been brutal) but give her a enemy to go toe to toe with and america has prove that she is a fucking monster.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
