WASHINGTON As the U.S. continued air strikes against ISIS in northern Iraq, retired Army Gen. Carter Ham said it looks as though the strikes are having an impact.

'I think the initial strikes are already having some effects,' Ham told ABC's Martha Raddatz Sunday. 'It seems to have at least given pause to the Islamic extremists.'

However, Ham said the situation in Iraq is difficult because the Iraqi army has no government to which it can be loyal, leading to a disjointed offensive against ISIS. Ham added that he agreed with President Obama that it's up to the Iraqi government to bring stability to Iraq.

As politicians, generals and ambassadors hit the talk shows Sunday morning, U.S. Central Command announced multiple airstrikes near Irbil from both planes and drones beginning at about 2:15 a.m. Eastern Time. The attacks destroyed three armed trucks and damaged two others, as well as blowing up a mortar position. The U.S. aircraft returned safely to base.

Christopher Hill, who served as ambassador to Iraq, told Raddatz there needs to be a forward-looking plan to deal with Syria.

'It's pretty clear that it's part of the situation in Syria that has metastasized into Iraq,' he said. 'I think the failure to focus on Syria, the failure to come up with a political or diplomatic way forward after all if Bashar al-Assad were hit by a bus today, there would still be a problem in Syria because no one knows what the country will look like in the future.'

Sen. John McCain, R-Ariz., said the situation is a threat to national security, and that ISIS is continuing to make gains. He called the airstrikes 'ineffective.'

'I would be launching airstrikes not only in Iraq, but in Syria against ISIL,' he told CNN's Candy Crowley. 'There is no policy, so there is no strategy, and therefor, things are going very, very badly.'

Sen. Ben Cardin, D-Md., said he is concerned about the extremist groups, but that it's important to work toward a representative government in Iraq, rather than try to solve the problem militarily.

'We will not become the Iraqi Air Force,' he told Crowley. 'I don't think we can take out ISIS from a military point of view from the use of our airstrikes.'
