It’s not even known if the dissenters yesterday were were from the SPD. It could also be that some from his own party voted against him. But unless the dissenters come forth, we will never know who it was, as the chancellor election is secret (and normally just a formality).
Another point to consider: Kerala in India has a very promising communist project going on. It already eliminated extreme poverty and has widespread support. Showing successes, it can serve as an inspiration for other projects in the imperial periphery (so called third world).
But Modi is a reactionary who could use the tensions with Pakistan to crack down on internal dissent and do reactionary things to the people of Kerala. So even without an escalation the current situation could lead to worsening conditions for the proletariat.
Even if that’s true (I’m not noticing it, even people who call themselves Antifa actively support the apartheid colony), it won’t have a noticeable effect on policy. The ruling class is much too invested in Isn’treal, a lot of people see only the Jews as victims of the holocaust and equate them with Israel. Combine that with the smug guilt culture (“we were bad but we have reflected on the past and now we’re better and know better than everybody else”) and a media Scape that practically only allows for Zionist talking points. I don’t see how the average germ*n will ever come to see the truth that Germany is again actively complicit in the genocide against the Palestinians by unapologetically supporting Israel
