5. We stay out of the internal affairs of other nations. America should conduct trade, travel and diplomacy with all willing nations. Intervention, however, always has unintended consequences and almost always gets us in trouble. For example, in 1953, our CIA helped overthrow Mohammad Mosaddeq, the democratically elected prime minister of Iran and installed the Shah of Iran, a ruthless dictator. The blowback from our actions was in large part responsible for the extremist Iranian Revolution of 1979, the taking of our hostages and the many problems we have had with Iran ever since. So much of our intervention makes no sense. We backed Saddam Hussein for much of the 1980s, and then twice went to war against him. In the 1990s, we bribed North Korea not to pursue atomic weapons with nuclear technology, and Kim Jong-il used that assistance to build several nuclear bombs.

Intervention simply does not serve our long-term interests.
