The IJN started the war with a parity or even superiority with the US and UK Pacific fleets thanks to the Washington Naval Treaties. They had an advantage in CVs because they realized early that they were game-changers. Are we facing any enemies remotely approaching naval parity with us? Is there a “game-changer” technology we’re not exploiting? Our only military rivals right now are the Sov, er, Russians and the PRC and we have them pretty handily outnumbered (on the seas) for now.
Islam is a threat. But it is not a military threat. The Arabs are military incompetents; the same is true of most Moslem militaries, with exceptions for the Turks, and maybe the Persians. Moslem nations can’t even build their aircraft, armor and major naval vessels. They ARE threats diplomatically, demographically, and legally (their greatest victories are ‘Lawfare’). Our open society and their money makes us hideously vulnerable in that fashion.
If we ever cut loose with our full military power, the only thing Moslems can do is die in huge quantities. Their only effective weapons are lawyers, diplomats, “civil rights organizations,” the media, and scads of money. Unfortunately, these are proving very effective, indeed, and no number of CVNs will counter them.
Because if they know we can do that, they will not dare attack. You get attacked when the enemy has decided that a surprise attack will bring them to parity.
