Unnamed sources reveal that the United States is already planning of mobilising its allied countries for expanding airstrikes in Syria.
The countries likely to be called upon include Australia, Britain, Jordan, Qatar, Saudi Arabia, Turkey and the United Arab Emirates.
In listing Australia and Britain, U.S. is expecting for these two partners to agree in an air campaign against the militants, the unnamed source told The New York Times.
They said that U.S. is also seeking the help of Turkey for it has military bases that would be efficient in launching any actions in Syria.
If this information is true, US President Barack Obama will still need to seek votes from Congress which is scheduled to open in September.
US lawmakers highly advised for Mr Obama to seek an up-or-down vote on whether U.S. should wage military action against the Islamic State.
"The president does remain committed to coordinating and consulting with Congress as he exercises his responsibilities and authorities as the commander in chief of the United States of America. The president recognizes that Congress has an important role to play. He also recognizes that he has an important role to play as commander in chief, and as the individual who's ultimately for the national security of the United States of America and the American people," spokesman Josh Earnest said in a meeting at The White House.
Meanwhile, the office for Prime Minister Tony Abbott said that the government will consider any request from U.S. based on whether there is an achievable overall humanitarian purpose and if Australia's role will be clear, specific and proportionate to the risk that entails.
"The government has been transparent about our intentions in Iraq. The prime minister has made it clear that Australia is ready to continue our humanitarian involvement in Iraq. Our response to any request from the United States, or other close allies and partners, will be based on whether there is an achievable overall humanitarian purpose and a clear and proportionate role for Australia as well as on a careful assessment of the risks," the office said in a statement.
The statement reiterates that Australia is not mulling on sending combat forces on the ground.
Australian forces were already previously deployed in northern Iraq to help distributing humanitarian aid to the minority Yazidi group stranded on Mt Sinjar.
