Attack from China?

Electro-magnetic Pulse (EMP) attack
Can we afford to wait and see what the ChiComs do?

China and Russia are two potential US adversaries that have the capability for this kind of attack. An EMP attack can either come from an intercontinental ballistic missile (ICBM), a submarine-launched ballistic missile (SLBM), a long-range cruise missile, or an orbiting satellite armed with a nuclear or non-nuclear EMP warhead. A nuclear burst of one (or more) megaton some 400 kilometers over central United States (Omaha, Nebraska) can blanket the whole continental US with electro-magnetic pulse in less than one second.

An EMP attack will damage all electrical grids on the US mainland. It will disable computers and other similar electronic devices with microchips. Most businesses and industries will shut down. The entire US economy will practically grind to a halt. Satellites within line of sight of the EMP burst will also be damaged, adversely affecting military command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR). Land-based intercontinental ballistic missiles will be rendered unserviceable in their silos. Anti-ballistic missile defenses will suffer the same fate. In short – total blackout. And American society as we know it will be thrown back to the Dark Ages.

Of course, the US may decide to strike first, but China and Russia now have the means of striking back with submarine-launched ballistic missiles with the same or even more devastating results. But knowing China's strategy of "active defense", when war with the US becomes imminent, China will surely not allow itself to be targeted first. It will seize the initiative as mandated by its doctrine by striking first.

China has repeatedly announced that it will not be the first to use nuclear weapons. But as an old Chinese saying goes: "There can never be too much deception in war." If it means the survival of the whole Chinese nation that is at stake, China will surely not allow a public statement to tie its hands and prevent it from seizing the initiative. As another saying goes: "All is fair in love and war."
After the detonation of the pulse bonb over the central USA we would be slung back into the 1920's in commerce and those who had access to horses and land could survive. Civil war would break out between those who had the means of survival and those who do not. "Head for the hills" might be the thing to do.
If we determine that Red China is a threat to our nation then it is imperative that our forces take out their capability to devastate us now!
