Very far fetched. Doesn't ring as anything plausible.
How a plan to attack the enemy at Golan (something in future) would be covered by a deliberate attack on an ally's battleship?
How the committed atrocities (something in the past) would be concealed by the same senseless action?
Sorry, but I see only two possible conclusions from what you said:
a) In your opinion, Israelis a stump stupid.
b) In your opinion, Israelis are plain evil.
You choose for yourself. I disagree with both.
