U.S. President Barack Obama has finally taken a stand against ISIS in a televised address on Wednesday. On the eve of the 13th anniversary of the 9/11 attacks, Mr Obama has formally stated conducting a series of airstrikes inside Syria.

But much like Syria divided by the ISIS and forces of President Bashar Assad, reactions to his momentous speech were equally split up as well.

U.S. Rep. Ileana Ros-Lehtinen, R-Miami said it was about time Washington took a definite stand on the matter because "it's long overdue." However, she didn't like the way the President is bypassing Congress, noting how the president wants Congressional approval for funds to arm and train the moderate rebels "but won't seek our approval to strike ISIL in Syria."

House Speaker John Boehner, R-Ohio found the president's approach lacking. "A speech is not the same thing as a strategy, however. While the president presented a compelling case for action, many questions remain about the way in which the president intends to act."

Republican Rep. Cory Gardner likewise said he expects the president to outline a "tangible, tactical action" towards the goal to eliminate the terror group.

Iowa Congressional Candidate Jim Mowrer said he does not support arming the rebels. "The area that I disagree with the President's strategy is arming the Syrian rebels that are fighting the regime. There is a civil war that exists in Syria, I have been all along, arming the Syrian rebels, in many cases, and we have bad guys fighting bad guys."

U.S. Rep. Alcee Hastings, D-Miramar believed the forerunner to eliminate the ISIS should be the Iraqi Government with "only support from the United States, regional partners, and the broader international community."

While Mr Obama said "no US boots will be sent on the ground," Sens. John McCain, R-Ariz., and Lindsey Graham, R-S.C., members of the Senate Armed Services Committee, reminded there have been in fact 1,100 U.S. troops sent back to Iraq.

An unidentified Pentagon official told Time there are actually 475 troops headed to Iraq right after Mr Obama said his speech.

Sen. Mark Udall, D-Colo., also a member of the Senate Armed Services as well as the Intelligence committee, said what's most important is to assure the American people and the global populace that the U.S. is not pursuing another open-ended conflict in the Middle East.

"I will not give this president - or any other president - a blank check to begin another land war in Iraq."

But as to when the expanded airstrikes will occur, only time knows.

An unidentified senior Pentagon official quoted by the Time said the actions will be made "at a prudent time as we continue to prosecute our comprehensive strategy against these [ISIS] terrorists."
