Not that I condone killing the wives and children, but I do foresee one critical flaw in the invaders plan. While in most countries, killing the top government officials would be like cutting the head off a snake. However, in America, killing the top government officials would be like taking a shackle off of a tiger. Big.Fn.Mistake.
I.E. it would be massive chaos. Exactly what they have planned. Besides, they are only going to eliminate the American government officials. The commie plants won't be disturbed. That means only about 20% of the officials have to be killed.
The 'chaos' will be completely managed, and turned into massive demand for CIVIL ORDER and restoration of SERVICES.
CIVIL ORDER will be installed, at a price. We will all be equal. Just like the Russians. Slaves to their government.
