Back in 1983, Grenada had a powerful military and posed a serious threat of conquering the world and imposing their dictatorship, and only the US, under the Great Reagan, were able to stop them. But peace did not last. In 1989, a new threat to the world arose, Panama, but Bush, Sr managed to subdue their quest for world domination. Shortly thereafter, in 1991, Iraq was prepared to first conquer the entire Middle East and take control of most of the world's oil, and again, only the US were able to stop them. Then, it was Yugoslavia that was close to conquering the entire world, but again, the US under Clinton managed to stop them. Then, on 9/11/2001, Afghanistan attacked the US and destroyed the World Trade Center. It took 20 years to topple that evil dictatorship, but the US finally managed under President Biden. During those 20 years, Libya became a serious threat, but Obama managed to lead the US military to victory, and the Libyan attempt at world domination was stopped.
But now we have the PRC and the RF. These are not great powers like Grenada and Panama, but only backward countries that wish to threaten the world. Obviously, Luxembourg would be able to take on both of these third-world countries who are nothing in comparison with Grenada and Panama, but Luxembourg is not willing, so it looks like the US of A will once again have to step up to the plate.
Fortunately, the PRC and the RF should not require nearly as much effort as Afghanistan, and the US should be able to subdue both in much less than 20 years. Chechnya and Dagestan and the other Republics in the RF will have their freedom, as will East Turkestan, Tibet, Hong Kong, and Taiwan.
