The Syrian civilian war has gotten completely out of hand. The country has seen a lot of civilian deaths and destruction of property.
The Syrian government has targeted the rebel groups resulting in this severe civil war and there is no end in sight as yet. Instead in its wake, Syria now has a lot of detainees in their jails who are undergoing a lot physical, emotional, and sexual abuse in the jails. There is debris everywhere now and too many dead bodies strewn all over the place in a place that was the perfect picture of love and prosperity. In its wake, Syria has left a lot of its civilians refugees in other countries with nothing to their names.
Iran, however, has for decades been funding, training and offering weapons to militia and terror groups while offering them shelter at the same time. Iran has had a tough stance on this issue despite efforts by outside forces to dissuade them from these practices. It hasn’t come out too clearly why Iran is doing this but it is a badly kept secret. The US government has tried unsuccessfully to get involved in stopping these vices but without much luck. What Iran has is really high tech weaponry and it has been arming itself for years now.
The government under the regime of president Assad was supported by the Iranian government since the Syrian war began. President Assad took on the presidency without much experience and without the support of Iran, this regime would have fallen as soon as the war started. Iran worked hard to provide whatever the government needed to fight against the rebels in Syria just so that the government is not overthrown. She has even help Syria train an army of 50,000 soldiers that will help protect the government from the rebels.
In the beginning, Iran only supported Syria by offering training for the regime forces. After a while, Iran escalated its support by actually sending their own troops to fight in the Syrian civil war. Another thing Iran did is to add into the chemical weaponry of Syria. She has sent her scientists to Syria and even provided the chemicals needed to build these weapons.
The arms cannot be transported by road nor by train, the only way Iran gets these weapons to Syria is by air. Iran and Syria have worked to create a safe corridor where they transport these arms. The US government has allowed only three airlines to get these weapons from Iran to Syria. Turkish authorities are said to have confiscated a truck which was headed for Syria and was full of weapons.
