ISIS, al-Qaeda split is finally over when a top Syrian opposition official and a rebel commander said that Islamic State and al-Qaeda militant leaders convened an assembly in northern Syria last week and agreed on a proposal to stop fighting against each other instead to work together against their foes.

The meeting happened in a small town of Atareb, west of Aleppo in Syria on Nov. 2 that started around midnight and ended until 4 in the morning. ISIS and al-Qaeda representatives sat down and hashed out a ceasefire between two splitting terrorist groups. The militant leaders also agreed to limited cooperation in their war against President Bashar Assad.

Earlier this year, the Islamic State, was disowned by the parent al-Qaeda group in Pakistan. Formerly known as al-Qaeda in Iraq, ISIS was rejected for its exaggerated viciousness and their territory war against the Nusra Front. ISIS and al-Qaeda immediately split and went to fight against each other. At the time, Time Magazine reported Islamic State's cruelty and "draconian" interpretations of the Islamic Law alienated many Syrians and drove a wedge between rebel groups.

Late last month, there have been signs that ISIS and al-Qaeda have ended their split and seem to have abridged their dispute with informal local truces. Associated Press reported the groups' new deal would involve a vow to cease fighting and unite in attacks in some areas of northern Syria.

US intelligence officials have been watching the ISIS and al-Qaeda closely and said a full union is not expected soon, if ever.  But cooperation would prove inadequate of merging the rival groups and experts believed any agreement between the once splitting sides could be easily undone.

The alleged ceasefire between ISIS and al-Qaeda could present difficulties for the US' strategy against destroying the Islamic State. The maneuver came amid reports that US President Barack Obama is rethinking the administration's Syria approach and whether it's possible to resolve the ongoing conflict without removing al-Assad. However, the reports were denied by the Obama regime, as reported by NYMag.com.

Meanwhile, if ISIS and al-Qaeda would end their split and work together, the terrorist groups will be more effective in Syria and a bloody war might possibly happen. And if the truce holds, it would definitely complicate matters for the United States in their fight to destroy the terrorists.
