מיר װעלן זײ איבערלעבן

It's yiddish. I really just am able to read the scrypt (I'm a really early beginner). I think it says:

”mir veln zey iberlebn!”

I don't know what zey (זײ) means, from my knowledge of german, I would interpret the sentence with that word omitted as "we want to survive".

Edit: It appears זײ is "them", so I imagine it says "we want to survive them".
