Germany is a democracy and their policy reflects the will of its people.

Sadly the truth. But when your only point of contact with the genocide is hearing IDF propaganda press releases on the news once a day it's not surprising.

Not to mention they would benefits from that sweet weapon industry money. 3 billions for the last 20 years

tl;dr: no.

Long version: Those profits most likely go to the Top 1‰ and we get nothing from it. Quite the opposite, in fact: Recently parliament removed the debt limit on defense spending (because Rheinmetal & Co. keep buying our politicians[1]). So now more money, that could go into crumbling infrastructure, will go to the pockets of those war proffiteurs.

We spend more money on our military than france and aren't even able to guarantee combat readiness. Meanwhile they were able to partipitate in multiple international law violating wars.

So no, we do not benifit from the sweet death weapon industry.

Exactly because they are a democracy, all people are allowed not to share the same opinion.
