Barack Obama says Iraq's current conflict is the result of sectarian divisions that have been allowed to fester.
The US President said on Thursday that he would send up to 300 military advisers to the country to aid the fight against the group ISIS.
"Some of the forces that have always possibly pulled Iraq apart are stronger now, (and) those forces that could keep the country united are weaker," he told NBC Nightly News.
"It is ultimately going to be up to the Iraqi leadership to try to pull the politics of the country back together again."
The Foreign Secretary has been clear on the threat of Isis, but he has ruled out the prospect of any UK military involvement in the crisis.
Iraq’s foreign minister, Hoshyar Zebari, is a natural diplomat. Polite, immaculately dressed, and blessed with a great memory.
Isis has paraded military equipment in Mosul it captured from when the Iraqi army fled in what some see as a "nightmare scenario."
