AUSTIN -- Over the weekend, the United States carried out five more airstrikes against Islamic militants in Iraq, bringing the total number of strikes to 115. The group Islamic State, commonly known as ISIS, is expanding and it's name change is part of that.

"Their reasoning for doing this is they want to show that they represent all Muslims across the world not just in Iraq," said Roy Casagranda.

Casagranda is an Associate Professor of Government at Austin Community College who has studied Middle Eastern affairs. He said the group, which has invaded Syria and Iraq, formed back in 2004 after the United States invaded Iraq and established a new government, getting rid of the country's existing police and military.

"All of a sudden you have all these well-armed, trained people who are non-employed, they're out of the system. They have no, no investment in the system succeeding. So the new state we established ended up becoming the target that they hated so much," explained Casagranda.

Experts say the U.S. war in Iraq created five million orphans, children who are now adults old enough to fight.

"They want vengeance," said Casagranda. "They have no job prospects, the economy in Iraq is in miserable shape, they haven't been educated because there's been war instead of normal, day to day life. And the Islamic State comes along and it says 'we're your future. We'll help you get vengeance, we'll give you a job, we'll give you a home.'"

But how does all this effect Americans? Casagranda said a large amount of the world's oil resources are in that region and a take over will effect the global market.

Plus the Islamic State has indicated it plans to attack U.S. allies Jordan and Saudi Arabia, which has the world's largest oil reserves.

"It is entirely feasible that we will be in another Middle East war in Iraq, fighting again," said Casagranda. "We have to prevent the fall of Saudi Arabia. We have a deal with the Saudis."

President Obama announced he is still weighing options on how to best deal with Islamic State. Officials in Britain have raised the country's terror alert due to the attacks.
