"The so-called moderate rebels are in cohabitation with the Nusra Front, so this is not surprising," Giraldi, a former CIA Case Officer and US Army Intelligence Officer who spent 20 years overseas working on terrorism cases, said on Wednesday.
The US government attempted to include the al-Nusra Front in the new ceasefire agreement in Aleppo, but the Russian government insisted on excluding the Islamist organization as unacceptable, Russian Foreign Minister Sergei Lavrov told Sputnik in an exclusive interview on Wednesday.
In reality, the opposition groups supported by Washington in their bid to topple Syrian President Bashar Assad, were almost totally under the control of the al-Nusra Front and its masters, al-Qaeda, Giraldi pointed out.
"Indeed, the so-called ‘moderates’ have largely been absorbed by the Nusra Front," he explained.
The Obama administration has been well-briefed about the true relationships between the secular bodies and the al-Nusra Front behind them, but it has refused to acknowledge these realities publicly, Giraldi observed.
"Washington is aware of the relationship, but for political reasons prefers to maintain that the two groups are separate," he stated.
In his interview with Sputnik, Lavrov remarked that the opposition seemed to be acting as a shield of protection for al-Nusra Front military forces fighting the Syrian Army in the Aleppo area.
However, the opposition groups had no military effectiveness by themselves and have been taking credit for activities that are actually carried out by the Islamists, he continued.
"It is part of the fantasy that our valiant moderates are having some impact in boldly confronting the Syrian Army," Giraldi maintained.
Moreover, Giraldi agreed with Lavrov’s assessment that the moderate Syrian opposition seemed to be shielding the al-Nusra Front.
Giraldi serves as Executive Director of the Council for the National Interest in Washington, DC.
