I’d be very worried if I were serving in the US militia, because he’s sounding off in all directions, and they cannot fight multiple ‘enemies’ at the same time as he appears to expect. The might of any one country is less than the combined might of others, and he would do very well not to upset China and Russia any more than he has done already.
The US is not small though The U.S. military ranks highly in overall strength and spending, but in terms of sheer active personnel, it's behind China and India, typically ranking third or fourth globally for manpower, while its defense budget is the world's largest by far, exceeding the next ten countries combined. The U.S. excels in technological superiority and global reach, maintaining numerous bases worldwide, but focuses more on advanced capabilities than massive troop numbers compared to countries like China, India, and Russia
