I don't know a great deal, but his stance on the Russia/Ukraine war concerns me.

Funny how his stance on Russia/Ukraine boils down to "Palestine should be free". Really makes you think

Don't see that objectionable stuff in there, really. I'm in favour of arming Ukraine. This article is several years old. It's not like Starmer stopped the war either. In fact, I think most Western European politicians have an interest in the war dragging on for as long as possible

Nah, he openly supports the annexation of Crimea (which means he supports the prosecution of Ukrainian speakers and Crimean Tartars).

The stuff about western leaders wanting the war to drag on as long as possible is a tankie conspiracy theory.

I think it's pretty obvious and I despise tankies. Look at what they're doing, not just what they're saying. Russia is a serious threat and they're finally seeing it. Better to have them fighting in Ukraine than their country

Edit: speaking of nasty conspiracy theories, btw, Starmerites calling Corbyn an antisemite was really the lowest of the low. Labour has been taken over by neoliberals fighting the left harder than the right

What they are doing (being slow and inconsistent with weapon deliveries) is driven is by fear and the receptiveness of their electorates to russian sabre rattling (even thought such strategies are openly described in key russian doctrinal texts) and russian propaganda.

I hate Corbyn, but I don't think he is an anti-semite (or maybe I just don't know enough). There is more than enough things to call him out for beyond vague notions of anti-semitism.
