Although stealth delays radar detection, its more important role is making stealth planes hard to target with weapons. The wide bands of radars that can detect the planes are not able to locate them accurately enough to target them with weapons. No stealth is invincible, so mission planning is also key.
When countries like China focus on heavily investing, initially it works well because they invest in productive things and this grows their economy. However, later, they run out of that many productive things to invest in, in which case they are robbing their citizens of consumption and outcompeting other countries’ manufacturing, but not gaining much actual new productive benefits. This leads to debt.
Bilateral tariffs like Trump is doing don’t work. The U.S. has a huge deficit because it consumes more than it exports. A global tariff could work by making goods more expensive and incentivizing people to consume, now relatively cheaper, domestic products. Bilateral tariffs just mean Americans will import cheap goods from country C and D instead of the heavily tariffed countries A and B.
Getting foreigners to invest in the U.S. hurts the U.S.. The U.S. has plenty of capital to invest and doesn’t need more. Additional investment means driving up the dollar, making U.S. goods less competitive internationally, and hurting U.S. exports.
China has debt to support investment. The U.S. has debt to support consumption. The system is out of whack and needs adjustment.
Calling a political opponent a communist is silly. Not even the Soviet Union or China called themselves communist. They called themselves socialist. Communism is when the productive surplus is controlled by the workers themselves. The government owning a business and deciding what to do with a surplus is just a government elite controlling the surplus instead of an owner or manager elite. Communism would be not a government elite or capitalist elite controlling the surplus, but the workers controlling the surplus. The socialist governments were supposed to be a transition phase to true communism. The closest things to this might be cooperatives where the workers also own the business, although those are done within a larger capitalist system.
The Muslims defeating China led to Islam being prominent in Central Asia and to paper technology leaving China and changing the world due to captured paper makers.
As the U.S. backs away from clean energy and limiting global warming on the president’s false belief that climate change is a hoax, China is stepping in as a leader globally, leading on the issue and selling its technologies and products to countries around the world. Despite its leadership and its massive renewable production, it still uses a lot of dirty coal. China’s clean energy partnerships around the world give it influence. The Trump-led U.S. is banking on past fuels and energy, while China is advancing into the future.
