Proposition: The United States has technological and tactical superiority but it must maintain these if it wants to avoid the consequences of being a super power in decline.
True. When you fight the United States, you are not fighting our Army, or our Navy, or Air Force or Marines, you are fighting them all at once, along with their technological superiority. Your Sukhoi fighters may be close to our F-35 in capability, your submarines sneaky, you may even have an aircraft carrier, although I hesitate to call what China and Russia have aircraft carriers. Your army may number in millions and you may have as many or more tanks. But to fight the USA you are fighting an interlocked and integrated system. You have to get past the eyes and ears of our satellites, AWACS and Hawkeye aircraft. You have to prevent our electronic snoop aircraft from hearing you. In the weeks before the actual confrontation, when posturing is the mode, our Rivet Joint aircraft in conjunction with other reconnaissance will have compiled a complete electronic order of battle on you. We did it to Saddam, which is why we were able to target his command and control structure so precisely. We are constantly updating the electronic order of battle on both China and Russia. Especially China.
Even though our forces are interlocked, if you manage to blind one source they can act independently. No communist or former communist government will trust its military to take initiative, as motivated and initiative-taking officers could threaten the political structure back home. Commies and other dictators always fear a coup more than the enemy. In training the Saudis to be an effective fighting force, we had to overcome the basic totalitarian structure which feared its best leaders. Trying to train troops at platoon level to overcome, improvise and adapt is hard when for years they have been trained by rote and varying from the rigid structure one degree was not tolerated.
The ability to take initiative when an opportunity arises is one reason why Israel has kicked Arab ass from day one. Even outnumbered several to one, with nations attacking from all sides the Israelis manage to seize tactical opportunities their opponents dare not try for fear of reprisal from their superiors.
Some nations can out range us (for now) with tube artillery, and they may have more artillery but nobody, and I mean nobody, ally or foe, can mass and control artillery fire like we can. Add in that with the possible exception of the Israelis, nobody does close air support and long range strategic air strikes the way we do, either. The wars in Iraq and Afghanistan have only made us better at conventional war; (other than Israel), what military right now is more experienced and blooded?
