Back in February 2012, Senators John McCain and Lindsey Graham publicly indulging in their favorite hobby, telling President Obama what he ought to be doing in the seemingly insolvable Syrian Civil War.
Their answer was to send American weapons to the anti-Assad rebels.

McCain's Folly
“I believe there are ways to get weapons to the opposition without direct United States involvement,” McCain told reporters at a news conference during a visit to the Afghan capital, Kabul,. “The Iranians and the Russians are providing Bashar Assad with weapons. People that are being massacred deserve to have the ability to defend themselves.”

“So I am not only not opposed,” he said, “but I am in favor of weapons being obtained by the opposition.”
In other words, the best policy was to return to the proxy wars of the Cold War.

(Nobody on the Republican side bothered to inform the senators that arming rebels in any country is a violation of international law. The International Court of Justice has in the past ruled that such shipments violated the UN charter. The last time this matter came up was curiously enough in the Reagan era with the covert arming of the Nicaraguan contras.)
