You forget we're talking about ISRAEL here. They don't care if ships approach the coast or are in international waters. They don't care if the ships are "enemy" or "ally." We know this from its unlawful, unprovoked attack on the U.S.S. Liberty which murdered 34 American sailors and injured nearly 200 more.
If Israel makes an unprovoked attack on these ships lawfully crossing through the Suez Canal, Israel deserves what comes next. Obama better not send more Americans to pay in blood for Israeli foolishness.
The attack on the Liberty was attacked in 1967, and I have heard this story used by you and many others on the web to justify cutting Israel off at the knees ever since. It is a simplistic and narrow view of the real situation in the Middle East, and it is a convenient ploy to avoid facing facts and realities overseas.
I ould point out that Israel views their security needs much differently than you or I do.
Kippis!
