The establishment of a military force to go abroad and overthrow governments does not appear anywhere in the Constitution of the United States, nor does calling for destruction of countries that do not themselves threaten America appear anywhere in Article 2, which describes the responsibilities of the President. Indeed, both Presidents George Washington and John Quincy Adams warned against the danger represented by foreign entanglements, with Adams specifically addressing what we now call democracy promotion, warning that the United States “should not go abroad to slay dragons.”
Since the end of the Second World War, the United States has proven to be particularly prone to attacking other countries that have only limited capability to strike back. North Korea was the exception that proved the rule when the Chinese intervened to support its ally in 1950 to drive back and nearly destroy advancing U.S. forces. Otherwise, it has been a succession of Granada, Panama, Afghanistan, Iraq, Somalia, Serbia, and Libya, none of which had the capability to hit back against the United States and the American people.
