TRILATERAL SUMMIT IN SYRIA...

Last nigth, there was an interesting dinner in Damascus. Iran's president Ahmedinejad, Hizballah's leader Nasrallah were hosted by Syria's president Assad.
Iran and Syria abolished visa application with each others. And both of the leaders teased US Secretary of State's statements about Syria. Hillary Clinton urged Syria to move away from Iran. Their respond to Clinton to cancel visas.

The Jerusalem Post, "Trilateral meeting in Damascus", February 26, 2010. http://www.jpost.com/MiddleEast/Article.aspx?id=169748

As it is known, US opened her embassy in Syria after 2005 assassination to Rafik Hariri who was PM of Lebanon. Why Syria was blamed about the attack.
Syrian-US relations developed since September 2008. US Secretary of State (Rice) and Syrian Foreign Minister Muallim attended the meetings between two countries' delegations in New York. New US administration sent two delegations plus Obama's special envoy Mitchell to Assad. And as it was underlined, US decided to re-open her embassy in Damascus. Also US encouraged Turkey to develop ties with Syria.
All these efforts by US seems to be closer with Syria. It's meaning to isolate Iran in the Middle East. Syria's approach to US, is not clear. Syria prefers to keep her alliance with Iran. Syrian-Iranian alliance sustains since 1980's. Hizballah in Lebanon is the tangible outcome of the alliance. Beside Lebanon's situation, Syria-Iran associates in Gaza. Their collaborator in Gaza is Hamas. Hamas' leader Mashal lives in Syria.
In spite of being closer with US, Syria does not give up her alliance with Iran. Sometimes Syria uses the multilateral relations as a bargaining tool in the region. But this policy has a risk potential for Syria and the all region.
Syria and Iran declared a Middle East without Israel and US. It can be commented bilateral alliance would fight against Western axis in the near region. Syrian-Iranian axis also target Arab regimes. The critical point is Lebanon. Lebanon's pro western PM Saad Hariri, agreed Hizballah's militant power against Israel. It can be decoded Hariri does not only share coalition government with Hizballah but also agrees to share state of Lebanon's sovereignty. Why Nasrallah who is the leader of Hizballah's existence is significant in Ahmedinejad-Assad summit.
If Lebanon can be converted as a Hizballahistan, it would a model to Arab world despite sectarian differences. Shia crescent's extension and main front is Lebanon.
Secondly, Iran's challenge to produce nuclear weapon would also create a pressure on Arab states.
Thirdly, Iran uses neighborhood relations on Turkey which is US ally and member of NATO. At least Iran tries Turkey to be neutral any further conflicts between Iran and Western forces plus Israel.
Fourth item about Iran to develop ties with Russia and China. Iran is currently an observer member of Shangai Cooperation Organisation. Beside the affiliation Iran has relations in Southern America. Venezuela is an important example of it. Venezuelan leader showed his support to Ahmedinejad several times. Iran attempts to be a part of anti Western world and achieves. It's tangible scores can be perceived in UN.
Global leader US and so called regional leader Iran would clash one day?
But Iran develops her process in each day. Iran aims to blockade Israel with Syria, Hizballah and Hamas.
Syrian-Iranian axis challenged with "trilateral summit" against US,Israel, Arab states and Western countries.
It has a potential for further conflict risks. And Turkey's situation is so critical about US-Iran clash. US raises her pressure on Turkey why US and Turkey are allies.
Turkish administration's calculations must be rational.
