I'm not questioning the validity of the article and I'm not defending Israel. But it's basic knowledge that (i) several first-world countries make a nice profit off of wars in the third world and (ii) almost all of these countries are liberal Western (or West-aligned) democracies. This is the reason why I don't understand why the author has singled out Israel here. Put it another way, could you name an arms exporter, which could be a company, country, etc., that doesn't sell to despotic regimes?
You're implying the author and associated publisher have some kind of agenda against Israel, if that's the argument you're making, then you need to present a little bit more proof. I don't see anything in the article that says "unlike other western countries… Israel does X, Y, AND Z bad things"
