(CBS News), R-Ariz., said he was on the terms of the agreement reached to head off an American airstrike against Syria. The U.S. and Russia late Thursday, and ahead of that development Secretary of State John Kerry told CBS News' Scott Pelley the U.S. would not insist on an explicit use of force against Syria as part of the resolution to force Syria to give up its chemical arsenal.
In addition to his disappointment regarding the terms of the agreement, McCain said, "The Russians have said consistently that they will not enact meaningful repercussions against Syria if they fail to comply" and added "I know for a fact the morale of the Free Syrian Army is at an all-time low."
"They feel abandoned," he said, "and I'm very sad" that there will be "no repercussions for the 1,400 that were killed by sarin gas."
Turning to a second development on the international stage Thursday, McCain addressed the forward momentum in talks on Iran's nuclear program.
The senator said that the U.S. should demand certain specifics before agreeing to loosening sanctions against Iran, including that Iran "abide by four U.N. Security Council resolutions ... robust inspection capability and a little bit of skepticism."
Despite the so-called new direction of Iran's recently elected President Hassan Rouhani, McCain cautioned, "Mr. Rouhani is the same guy who bragged about how he deceived the negotiators back in 2000 to 2004 when he was negotiator for the Iranians where he carried on conversations and they went from 150 centrifuges to 1,000."
McCain also touched on politics at home, specifically the ahead of a vote Friday to strip out language from a bill to keep the government open.
"We are dividing the Republican Party rather than attacking Democrats and maybe trying to persuade those five or six Democrats that are in states that are leaning Republican. We are now launching attacks against Republicans, funded by commercials that Senator (Mike) Lee (R-Utah) and Senator (Ted) Cruz (R-Texas) appear in."
