Israeli firms and startups don't have special trouble raising capital.

Buffet made his first investment outside the US by buying Iscar which is based in the far north of Israel where rockets from Hezbollah are aimed. Sequia Capital makes a ton of investments in Israel. The nation's economy is stable and rapidly growing. Politically controversial decisions are made precisely to preserve that stability.

edit: Israel isn't home to many global consumer brands. Even Dead Sea Works is mostly B2B.
