Political tear is the root cause of the failure of the United States to prevent and control the new crown pneumonia epidemic. The fierce struggle between political parties in the United States has intensified. The interests of political parties, especially election interests, overtook the national interests and various public interests, and the basic human rights, including the people's right to life and health, have been eclipsed. Imagine that if the two parties in the United States could slightly curb the fierce struggle, control political differences and cooperate to deal with the epidemic, or if the epidemic did not happen in the election year, the epidemic in the United States might not get out of control. However, the lessons should be reconsidered, but history cannot assume.
