Well, the Americans helped the Kurds until they didn't.

Americans have provided support to militias from various Middle Eastern ethnic groups throughout history. However, in recent years, the United States has primarily allied with and supported the Kurdish militias in the region, particularly in the fight against the Islamic State (IS) terrorist group.

To arrive at this answer, you can consider the following factors:

1. Historical context: In the past, Americans have supported various Middle Eastern ethnic groups, depending on the geopolitical climate and national interests. For example, during the Cold War, the United States provided aid to Afghan militias, including those composed of ethnic Pashtuns, in their resistance against the Soviet Union.

2. Recent conflicts and alliances: Since the rise of IS in the early 2010s, the United States has collaborated closely with Kurdish militias, particularly the People's Protection Units (YPG) in Syria and the Kurdish Peshmerga forces in Iraq. The Kurds have been recognized for their effectiveness against the IS threat and have received support from the United States in the form of military training, weapons, and air support.

3. Political considerations: The Kurdish population in the Middle East spans across several countries, including Syria, Iraq, Turkey, and Iran. In some cases, such as in Turkey, where a Kurdish separatist movement has been active, U.S. support for Kurdish militias has strained relations with the Turkish government. However, it is crucial to note that while the United States has supported Kurdish militias, it does not necessarily imply support for Kurdish separatism or independence.

It's essential to keep in mind that alliances and support can evolve over time due to changing circumstances and political considerations. Therefore, it is always prudent to refer to current events and official statements for the most up-to-date information on American alliances and support for Middle Eastern militias.
