The people of Taiwan shouldn't live under the threat of missiles. I don't think anyone in this world should live like that. The US government doesn't recognize Taiwan as an independent country because they do not want to disrupt the status quo. The US agreed with China on "The one China rule" during the cold war. This was a way to derail another country's support for the USSR. And this has been the status quo since Nixon was in office.
Being American, it is easy to understand why Taiwan doesn't want to become under communist rule. But in all reality, this is a Chinese matter that should be resolved by the Chinese/Taiwanese people without going to war.
They need to understand each other and that they both need one another. Especially China, they believe their recent economic gain is caused by the people of China, which is totally false. If you go to Shanghai, China and walk down a commercial street, you will notice over half of the businesses are owned by people from Hong Kong or Taiwan. They need to understand China didn't grow so fast on their own. The people of Hong Kong and Taiwan helped open China's doors to the world.
