Usa and israel backed terrorists

You may want to watch the video first, which goes into how the Kurds have traditionally been used as pawns by the US.

The Kurds have been persecuted by virtually every nation state around them. However, just because the US is now attempting to use them again doesn't mean they're terrorists, nor that they support Israel. Left to their own devices, they were able to organize Rojava, which was the latest effort at a federated horizontal society.

Those same Kurdish groups are fairly deeply intertwined with Palestinian resistance groups as well:

The Palestinian and Kurdish liberation movements have long and deep connections, the legacy of which remains in the thinking of the current Rojava Kurdish leadership. After the PKK leadership’s flight from Turkey to Syria in 1980, it was the Palestinian quarter of Damascus that covertly sheltered PKK militants, and it was the Palestinian Democratic Front for the Liberation of Palestine who provided a lifeline for the PKK and gave them training in guerilla warfare. It was there in Lebanon, fighting alongside the Palestinians, that the PKK saw some of its first combat deaths—not against Turkey but against Israel. Others would later be captured and interrogated by both Israeli troops and Turkish intelligence officials. This mutual solidarity will not be forgotten.

On the Kurdish side, both the Kurdistan Communities Union (KCK) and SDF leader Mazloum Abdi have condemned Israeli violence against Palestinian civilians and have supported the establishment of a Palestinian polity (whether as a state or a democratic confederation) and senior figures in Rojava such as Polat Can have written of their opposition to Zionism.
