Wow. The DSA *hasn't* pledged solidarity with Hamas yet?? I'm stunned.
Most of the various DSA groups have long been allied with PFLP and DFLP (groups 3 and 4 of the Oct 7th attack and the only surviving communist backed Palestinian terrorist groups from the Cold War era).
In 2013 PFLP joined the Iranian backed axis. In 2015 PFLP-GC joined the Syrian Army in depopulating the Yarmouk Palestinian refugee camp in Syria. Killing or displacing over 100,000 Palestinian refugees.
