Mosul: Open Trap

Robert Michael Gates, Former United States Secretary of Defense, wrote in his book “Duty” that terrorism in Iraq was supported by groups of Iran and Syria. So this assumption exists that now also Syria and Iran are the major supporters of militant group, “ISIS”.
Supporting militant group “ISIS”, Bashar al-Assad could have put his fight against opposition under the title of fight against terrorism; and thus, legitimize it. On the other hand, by transferring “ISIS" terrorism from Syria to Iraq, Bashar al-Assad could actually alter the playing field and divert looks from Syria to another point. But, what needs to be considered is that now two thousand military forces of Iran have arrived in Iraq in order to support the government and fight against terrorists.
Some points are so important about this subject:
Iranian military forces entered Iraq, are a population of Army of the Guardians forces, and not Iranian Army (in other words, a Mafia organization which have found new linking bridges with Arabic countries, including Kuwait, and Qatar, as well as groups from Russia and the US). 
According to the fact that Iran always avoids military presence to maintain peace in the region, including Iraq's invasion of Kuwait, the fight against terrorism in Iraq, Afghanistan and Pakistan; it can be concluded that this behavior of Iran doesn't have any adaptation with its previous behavior in the international arena. 
So, what is important is, understanding Iran's intention of presence of Army of the Guardians in Iraq. 
Finally, there is the assumption that Army of the Guardians is candidate for the project of “heating of the geography” in the Middle East, again; if this assumption is correct, it must be said that Mosul is a trap for Washington.
