“but Serbia has a military security pact with Iran.”
And your point is ???
Serbia has military/security pacts with several countries...including the US. The Serbian army even trains with Americans in Ohio (see: http://www.vojska.mod.gov.yu/eng/MVS/Ohajo/01.07.2007_bolja_komunikacija_sa_svetom.html)
Serbia also contributes to UN peacekeeping forces in Libera, Ivory Coast and DR Congo.
My point is that the protests by Serbs that the US supports “jihadists” ring hollow because the Serbs are military allies with the most evil jihadists on Earth.
