Anyone with any sense of military logistics or tactics will tell you that there is no way in hell Russia or China are ever going to invade the United States without considerable cost to their own countries and resources. Two great oceans separate us from them, and America is the most armed, and the craziest country in the entire world.. who in their right mind would want to invade this first world ****hole?
And they don't have to, anyway. The unconventional and alternate wars they've waged against us have been devastatingly successful. Russia runs troll farms out of eastern Europe that reached 140 million Americans and interfered substantially with our 2020 elections by sowing doubt, confusion, and political division that continues to this day. This was all based on a paper General Valery Gerasimov, Russia?s chief of the General Staff, comparable to the U.S. chairman of the Joint Chiefs of Staff wrote in 2013: “The Value of Science Is in the Foresight,” in the weekly Russian trade paper Military-Industrial Kurier. Gerasimov took tactics developed by the Soviets, blended them with strategic military thinking about total war, and laid out a new theory of modern warfare. He basically wrote: “The very ‘rules of war? have changed. The role of nonmilitary means of achieving political and strategic goals has grown, and, in many cases, they have exceeded the power of force of weapons in their effectiveness."
Think about that for a minute. China and Russia has been far more successful with their attacks on our democracy through social media than if they were to attack us physically.
