A political commentator says the plots by the US and its allies to destroy Syria through supporting militancy in the Arab country have failed as the foreign-backed terrorists are now “self-destructing".

“This so-called democracy-building was aimed to turn Syria into a failed criminal state like what’s been done in Libya,” Randy Short, a human rights activist from Washington, told Press TV on Sunday.

Commenting on the infighting between rival militants in Syria, Short said when guns are given to “criminals and dogs and killers and rapists … that have no conscience and no morality and no ideology, of course they’ll kill each other.”

Qassem Saadeddine, a spokesman for the so-called Free Syrian Army (FSA) militants, said on July 11 that a splinter Takfiri group had killed their senior commander Kamal Hamami, known by his nom de guerre Abu Bassel al-Ladkani, following a meeting with him to discuss battle plans in the Syrian port city of Latakia.

Over the past months, rivalries and infighting have been on the rise among the highly-divided militants operating inside Syria.

On June 5, dozens of militants were killed and wounded as violent infighting broke out between several Takfiri groups in Syria’s northwestern province of Idlib, according to locals.

Short further cited the accusations that Damascus had used chemical weapons in the battle against the militants as an example of the desperate measures by the US and its allies to make up for their failed policies in Syria.

“I’m convinced that they’re going to try something more desperate to prevent being embarrassed that their policy - their effort to destroy Syria - has failed,” the political commentator said.

Foreign-sponsored militancy in Syria has taken its toll on the lives of many people, including large numbers of Syrian soldiers and security personnel, since March 2011.

Western powers and their regional allies including the Israeli regime, Turkey, Saudi Arabia and Qatar have joined hands in supporting anti-Syria militant groups, including al-Qaeda-linked terrorists, to destabilize Syria and overthrow the government of President Bashar al-Assad.
