In the months and years following 9/11, the U.S. never knew how to retaliate. We went after Iraq, run by a dictator who had nothing to do with the attack on America, and Afghanistan, a nomadic country inhabited by tribes and gangs. Iran was known to be the world’s # 1 sponsor of terrorism, and we did NOTHING.
The Bush administration was obsessed with settling a score with Saddam Hussein, and was too cowardly to attack Iran because the left loves Iran and Bush wanted leftists to like him.
Obama was actively on the side of Iranian terrorists and Biden was his demented puppet; both regimes gave billions to Iran.
Trump has done the right thing, but it took America 25 years to make it happen. The Democratic Party is now at least as great an enemy of America as the Iranian regime was. Watch how they (and their media, universities, mayors, Senators and governors) respond.
