Ariel Sharon was the prime minister of Israel in 2002. Netanyahu was a civilian. You seem to be unable to tell these two very different people apart. I suggest going easy on the green stuff.

Current prime minister, former and future prime minister, that's an irrelevant distinction here. Clearly the Israelis thought the Iraq war was in their interest, which is the original claim here, and is clearly evidenced by Israeli attempts to lobby in favor of the invasion.

This is demonstrably false. Ariel Sharon lobbied against the invasion.

Netanyahu’s role is extremely relevant. There’s a big difference between a civilian’s personal opinion and official state policy.

Your original claim is false. End of story.
