9/11 gave the United States a strong reason to interfere in the Middle East and West Asia. Syria also broke out into a civil war following the US's intervention.

The war has lasted more than five years and brought huge suffering to the nation and its people. Analysts believe the long-term intervention of the US and other outsiders is one of the key factors in the Syrian crisis.

A Syrian scholar said the US and its Middle Eastern allies have provided significant military support to Syrian opposition forces.

Many of the weapons have ended up in the hands of terrorist groups. He said instead of fighting terrorism, the US is encouraging its "proxies" to cause trouble in the region.
