The need for Syrian Conflict1866590
During the ongoing conflict in Syria between the Bashar Al-Assad forces and also the rebel army it could possibly have been observed that "Syrian conflict" became one of the extremely crucial cases for the world. Both Vladimir Putin and Barack Obama are making their points in showing that it's in their countries interests to do something. Therefore, it poses the issue why your situation in Syria can be so very important to Russia as well as the United states.
Firstly, it can be worth mentioning the strategic geographical and political location of Syria - It's use of Med and is during four important countries/regions: Israel, Iran, Kuwait and Caucasian states. The initial a couple of them have hostile relations and especially under the presidency of Mahmoud Ahmadinejad the conflict seemed very plausible. Syria can be found between those countries and Iran could be the strongest ally at the center East, which can make them a very situated near commercial establishments country.
The past two countries, Kuwait and Caucasian states are relatively near to Syria. The most important thing, is the fact that destabilization of Syria as well as the large numbers of Islamic extremist mercenaries (who partly constitute the rebel army) could have effect on situation in those regions (Kuwait - which can be very important mainly because it continues to be your fourth biggest oil exporter to the USA in last 20 years) and former Soviet Caucasian states, which have already causing problems because of the activity of their extremist groups. Hence, both Russians (avoiding destabilization and increase of influence of extremist groups in Caucasian states - mostly Chechen groups, that are actually Muslim) and USA (supporting Israel against Iran and protecting their economic curiosity about the center east) are incredibly worried about the donate to syria. Obama feels a lot of pressure from your Israeli government (and apparently the Kuwait government that is supporting the rebel army right from the start), who emphasize the threat of Iran for the complete Middle East.
The second, very important aspect is the control of the med Sea. The Russian Naval Base in Tartus established in 1971 under agreement of Soviet Union and Syrian governments may be basically named because only opposition to USA/NATO domination within the Mediterranean and beyond. In case of failure of Bashar Al-Assad, a good Russian base could be put under question with the new government. Additionally, Putin would loss his only ally from the Middle-east region what is actually more, a profit provider as Russia may be the biggest exporter of weaponry for Syria.
Lastly, Obama follows the ideological superiority of USA over other countries and thus feels obligated to intervene in Syria. The conflict in Syria could be described not only as conflict between Al-Assad and rebel forces, but also as being a conflict within the diplomatic domination between Putin and Obama. Every possible closure in the Syrian conflict is sure to have major impact on both relations between Russia and USA as well as the future of the Middle East.
