Military leaders from more than 20 countries were in the United States this week for talks with President Barack Obama. They spoke about U.S.-led efforts to defeat the Islamic State militant group. The militants now control large parts of Iraq and Syria.
President Obama told the leaders that he was concerned about the gains of Islamic State forces in western Iraq and near the Syrian town of Kobani. But he did not suggest any changes to what he called "a long-term campaign" against the militants. He said the campaign would include "days of progress and periods of setback," but would not involve what he called "quick fixes."
Mr. Obama said the situation in Kobani shows the threat from Islamic State forces. He said the U.S.-led coalition is united on wearing down and destroying the militant group. But he noted the operation is "not simply a military campaign."
"This is not a classic army in which we defeat them on the battlefield and then they ultimately surrender. What we're also fighting is an ideological strain of extremism that has taken root in too many parts of the region."
Some critics have questioned the plan of action against the militants. Last Sunday, U.S. Senator John McCain noted the apparent success of Islamic State forces in battle. The United Nations reported on Monday that up to 180,000 people fled fighting in western Iraq after militants captured the city of Hit.
The United States has intensified its bombing of Islamic State forces in Iraq and Syria. But observers are calling for consideration of ground troops to strengthen the campaign against the militants.
In recent weeks, Turkey has come under pressure to send its troops into northern Syria. Militants and Kurdish forces there are fighting for control of Kobani. The Kurdistan Workers' Party has called on Kurds to defend the town. But the group -- known as the PKK -- has battled the Turkish government for 30 years in its campaign for self-rule.
UN officials and Kurds have urged the government to permit creation of a safe area so that Kurdish volunteers can help those defending Kobani. But Turkey distrusts the PKK, and fears being pulled into the fighting. Earlier this week, Turkish aircraft attacked Kurdish rebel bases in Turkey. The Turkish military said the raids were meant to answer attacks on one of its bases.
Two other countries -- Saudi Arabia and the United Arab Emirates -- are active in military operations against the Islamic State. Saudi Arabia has long competed against Iran and its allies, including Syrian President Bashar Assad.
The U.S. government wants the Syrian leader to surrender power. It has accused him of using acts of terrorism against his own people. Both the United States and Saudi Arabia support Syrian rebel groups they describe as "moderate" -- in other words, they are opposed to Mr. Assad and the Islamic State.
Robert Blecher is with the International Crisis Group. He says the Syrian rebels are having trouble believing members of the coalition. The reason: coalition forces have been attacking Islamic State fighters with the approval of Syrian officials.
"That's their line, but it's awfully hard to hold up that argument when you have rebels on the ground who are saying, 'OK, if you want to support us, why aren't you going after the regime?'"
He warns that U.S. support for President Assad, whether real or not, could push the rebels away from the coalition.
For now, Saudi Arabia remains firm in its opposition to the Assad government. It says the first goal should be defeating the Islamic State.

本周，来自20多个国家的军事领导人齐聚美国，与奥巴马总统举行会晤。他们讨论了美国领导的打击伊斯兰国激进组织的努力 。这些激进分子现在控制了伊拉克和叙利亚大部分领土 。
奥巴马总统告诉领导人们，他对伊斯兰国力量在伊拉克西部和叙利亚城镇Kobani获得的胜利表示担忧。但是他并未提出对打击这些激进分子的“长期行动”作出改变 。他表示，行动将包括“进展期和挫败期”，但是不会有“快速解决方法” 。
奥巴马总统表示，Kobani的形势表明了来自伊斯兰国力量的威胁。他表示，美国领导的盟军在挫败和摧毁激进组织方面团结一致 。但是他指出，行动不仅仅是军事方面的 。
一些批评家对打击激进分子的行动计划提出了质疑。上周日，美国参议员约翰·麦凯恩指出了伊斯兰国力量在战争中取得的显而易见的胜利 。周一，联合国报道称，激进分子占领了Hit城之后，超过180,000人逃离伊拉克西部的战争 。
近几周来，土耳其承受着向叙利亚北部派遣军队的压力。那里的激进分子和库尔德力量正在争夺对Kobani的控制权 。库尔德工人党呼吁库尔德人包围该城镇 。但是库尔德工人党武装组织成员(PKK)30年来一直与土耳其政府斗争，争取自治 。
联合国官员和库尔德人敦促政府允许建立一个安全区，这样库尔德志愿者就可以帮助保卫Kobani。但是土耳其并不信任PKK，担心被卷入战争 。本周早些时候，土耳其飞机袭击了土耳其境内库尔德叛军基地 。土耳其军方表示，袭击旨在对政府基地遭遇的袭击作出回应 。
美国政府希望叙利亚领导人上交权利。美国指控阿萨德对自己的人民实施恐怖主义行动 。美国和沙特阿拉伯都支持他们所说的“温和的”叛军，换句话说，他们反对阿萨德和伊斯兰国 。
Robert Blecher是国际危机组织工作人员。他表示，叙利亚叛军难以相信盟国成员 。原因是：盟军力量是在叙利亚官员同意的前提下袭击伊斯兰国战士的 。
