Australia is convinced that Russia and China will join the international coalition against the Islamic State of Iraq and Syria, or ISIS, following the extremist group's boldness in issuing terror threats. According to reports, the threat of ISIS to global security may lead other nations to join the coalition.

A United Nations Security Council meeting is scheduled on Sept 19 in New York to be chaired by U.S. Secretary of State John Kerry. Julie Bishop, Australia's foreign minister, who will also be attending the meeting, said military strikes against ISIS and other terrorist groups would be done to aid Kurdish and Iraqi forces.

In an interview with the Wall Street Journal, Bishop said she hopes China and Russia would be able to see the need for an international coalition. China and Russia are both members of the Security Council, joining Australia, Britain, France and the U.S.

Bishop urged other countries, especially those with strong military capabilities to join the coalition. She said it was all about "rolling back a terrorist threat" in the Middle East. Reports said a group of 26 countries have expressed their support in the fight against ISIS in a meeting in Paris. The coalition vows to fight the Sunni extremist group "by any means necessary."

Australia has been vocal in its support for U.S. President Barack Obama's plan to launch airstrikes against ISIS in Iraq and Syria. Prime Minister Tony Abbott has announced that the country will be sending its warplanes and military troops to the United Arab Emirates to be placed on standby.

Mr Abbott has called ISIS a "death cult" and he intends to help in stopping the militants from spreading their "medieval-style beheadings," reports said. Australia has been aiding the U.S. in rallying support for the coalition as it prepares to take presidency of the UN Security Council in November.

Meanwhile, a trio of security advisers has warned Mr Obama in a congressional committee meeting that ISIS and Al Qaeda are competing to become the leading terrorist group in the world. The security experts warned the rivalry could cause one of the groups to strike the U.S. first.

Secretary of Homeland Security Jeh Johnson, FBI Director James Comey and National Counterterrorism Center Director Matthew Olsen believe it is possible. Comey said any terrorist group would not be known as the leader of a "global jihad" if it will not attack the U.S. first.
