It saddens me to hear this, however Mamdani has nothing to do with Cuba, Venezuela, or Israel (other than divestment initiatives, which other DSA representatives have supported for the most part). He is running for NYC mayor not the "Department of War". Politicians are not thought leaders in the US, they are a tool to be used for legislation. If these are the words he needs to say to bring material change to the people of NYC, its unfortunate but may be worth it. Him speaking like a maoist third worldist isn't going to change much.

Real change in the US will not come from a politician, it will come from the people.

I believe we will see more of this as an effect of USA tariffs. Why would anyone care about the American blockade when they are getting tariffs anyway? I'm hopeful this will lead to improving the material conditions of the global south.
