About 1,000 packed the McKimmon Center to hear Paul talk about his campaign for liberty.
"We're getting into too many wars, we're getting into them carelessly and we're not doing them in the proper manner," Paul said.
He was especially critical of President Barack Obama's decision to join other allies and intervene in Libya, saying the action is unconstitutional since the President did not seek permission from Congress.
"Where did our President get permission this time?" Paul asked. "[The] same place Harry Truman did in order to go into Korea. They didn't come to the US Congress. They went to the United Nations to get the permission to put us to war."
But President Obama reassured the country Monday night that the U.S. is not at war.
"The United States has not acted alone," the President said during his speech. "Instead, we have been joined by a strong and growing coalition."
A coalition of countries whose purpose, according to the President, is to protect the Libyan people, but Paul says the U.S. should return to basics and focus instead on domestic issues.
"Don't get involved in alliances, don't get involved in the internal affairs of other nations," Paul said. "Don't go into nation building. Mind our business and take care of our own country first."
It's worth noting that there were many people in the audience with signs saying Ron Paul for President in 2012. Paul says he still hasn't decided if he'll be running.
