Coincedentally most of my favorite speed (or speed influenced albums) are European:
Some of my favorite speed bands were (not limited to the following):
Pestilence (though they crossed into death)
(note many are linked to death metal; and I'm going to leave Bathory and company in the black metal camp):
These are bands that just give a run down of what I listen to in the speed genre. I go for the darker bands in the genre for the most part and just never heavily gravitated towards those heavily politically oriented bands (which is where a lot of the leftism came in).
Speed/thrash was the first genre of metal I got into and for that I will forever pay it my respects, but overall it's not the genre of music that enamors me and I pull out a speed cd when I just want to remember old times or just feel like listening to strict metal. The thrash bands that still are on my playlists are all those listed above and it's mostly just Destruction, Sepultura, and Possessed. These days I'm listening to styles of music that are in the vein of things I listened to when I was about 4 and 5 thus I have more ambient, folk and classical playing along with noise, industrial, and black metal. Really death metal was big for me a couple years ago and when I finally accepted black metal it became the ultimate form of metal oriented music for me (though black metal is so much more which is why I grew into it so deeply). If any metal style is going to be in my collection for life it's black metal followed by some death metal bands and a few thrash/speed bands (mostly just the ones in my list, give or take a few more).
I'm not much for most of those california speed/thrash bands who were into skating and such, which reminds me, was Suicidal Tendancies considered thrash or speed metal?
