Qatar is the next aim for Russia and Iran

The Strategical Importance of Qatar
The geopolitical position of Qatar as a coastal country in the strategically important Persian Gulf makes it one of the most preferable American allies in the region. There is situated a large Qatari air base, operated by the United States. Qatari special forces have been trained by NATO countries, and its security services have strong ties with their western counterparts.
Its economy is based on oil and gas extraction. Economically, Qatar is the main American ally in its energy strategy. Its geo-economic goal is to decrease Europe’s dependence on Russian and Iranian oil and gas supplies. Before the Syrian War, Qatar planned to construct a major gas pipeline to the Mediterranean Coast through Syria, but that proposal was rejected by the Syrian government. Syrians preferred the analogous Iranian plan, and this was one of the pretexts of the war.
Qatar’s TV network, Al Jazeera, is the main television network in the Middle East, and is an important tool used in information warfare.
Qatar’s support for extremists
During the Arab Spring, Qatar with Turkey backed the forces of the Muslim Brotherhood. Common ideological and geopolitical lines strengthened bilateral ties between the countries.  Like Turkey, Qatar is often blamed for being one of the main sponsors of terrorist groups including ISIS and Jabhat-Al-Nusra.
Qatar's official state religion is Wahhabi Islam. Qatar funds, in at least some form of assistance through its private and state institutions  —  whether sanctuary, media, money or arms —  the Taliban of Afghanistan, terrorists in Syria and Libya, and allies of the Muslim Brotherhood across the region.
Qatar’s role in the backing of terrorists around the world is recognized by its American allies. United States Treasury officials have singled out both Qatar and Kuwait as “permissive jurisdictions” for terrorist fund-raising. No actions against Qatar are undertaken.
Qatar supports the same extremists as Turkey and is backing Turkey in its confrontation with Russia. In the case of the war, open or not, it will increase its assistance to Turkey and anti-Russian Islamists, not only in the Middle East, and will involve itself more openly in the Syrian War.
Forecast

Russia clearly understands the role of Qatar, and so it may become one of the primary military targets.  Unlike the Turkish case, these actions can be supported by Iran which is Qatar’s main enemy in the region. They are at odds not just over Yemen and Syria. The very existence of a Wahhabist and US-backed Qatar, guarding the Persian Gulf, is a threat to Iran’s national security.
