Difficulty of Modern Hebrew

[aindreas]

Found nothing of this sort tagged, so apologies if it's been discussed before. How difficult is it for a native English speaker to gain a basic proficiency in Modern Israeli Hebrew? What are the more challenging aspects? Troublesome grammar? Foreign vocabulary?

I've been wanting to learn for awhile now, but am wondering where I'd run into the most troubles. I speak passable German and Spanish, if that changes anything. Would appreciate any thoughts. Thanks!
