Half the world may not like the USA but half the world is not going to go to war with us either. India may not like us but they are not going to marshal any troops to fight us. China has their own economic problems, just as other hostile enemies have.
People are very 20th century in their understanding and thinking on war.
India, with 20% of the world's population, is joining with China, another 20% of the worlds population. Which is joining with Brazil 3%, Saudi Arabia, Iraq, and Iran along with Russia. By population that's about 1/2 the world.
Understand the US is pretty lonely over here and has only 5% of the worlds population. Yet we consume a disproportionate amount of goods, mostly from other nations. All that trade, could be turned off like during Covid... And that crashed our economy which was propped up by printing money. Do you recall. Now imagine, no propping up, no more borrowing. The spigot of energy and goods is turned off...
By resources, China is the global industrial hub. Oil, that's Russia (#2), Saudi Arabia (#3), China (#5), Iraq (#6), Brazil (#8), Iran (#9). Economically, these nations can drop the dollar, refuse to trade with the US, and destroy the US economy. In about a few months. By food production, the Top 5 include China, Russia, Brazil, India.
This isn't theory. Research the BRICSS nations and currency.
Militarily, Russia and China are extremely powerful and essentially peers to the US. NATO strong but not much help to the US, based on history. The US carries them economically and militarily.
India may not like us but they are not going to marshal any troops to fight us. China has their own economic problems, just as other hostile enemies have. While we currently do not have much in the way of manufacturing but the USA can certainly ramp up very quickly, in an emergency. True, many nations are not in love with America, they also know what would happen if America lost a conventional war. The other countries would be the next in line.
Nations are going to pick teams and they'll pick the likely winners. The US has not done much for the world in terms of engendering loyalty. Look at Iraq. We invested 8 years and trillions there to liberate Iraq. Guess whose team they just picked. China. Afghanistan kicked us out and is aligned with China.
The US is particularly vulnerable to attacks from within. In 2023 we have experienced grid attacks, very suspicious train derailments, factory fires and explosions, livestock massacres, and so forth. If we get deep into war, it's highly likely that terrorists from within attack our nation daily in significant ways to totally economically cripple us and demoralize us while killing endless numbers of people. I won't list any ideas but use your imagination. You bet that China has cells living here waiting to be activated.
People need to WTFU. The west and the US is about to get our rear ends kicked into the 19th Century. By half the world in population and the bulk of the economic and military power.
We are dangerously in the first stages of a world war that the US is going to lose and lose badly.
