How much more IP has Israel stolen than China?

Israel doesn't have a habit of threatening US interests. Israel didn't attempt to shoot down our aircraft and hold our aircrews hostage. Israel isn't threatening Taiwan, propping up North Korean dictators or funneling weapons to Darfur. Israel is actually a partner in security as opposed to an opponent. Israel isn't manipulating currency or holding world financial markets hostage. I guess Israel bashing is fashionable. By the way, you have no evidence that Israel has stolen more IP than China -- that's just a nonsensical claim.

"Israel didn't attempt to shoot down our aircraft and hold our aircrews hostage."

But they did attack US Navy: http://en.wikipedia.org/wiki/USS_Liberty_incident

"Israel isn't threatening Taiwan"

But they do threaten and attacked their neighbours. By the same token, China is not threatening Syria.

"propping up North Korean dictators or funneling weapons to Darfur"

Israel is one of the biggest arms dealers in the world, and a lot of those weapons go to the hands of various dictators, e.g. in Africa.
