There's solid evidence for Mossad ties with the KDP since 1959.

Israel has a strong and special relationship with the Kurds, which extends to recent times when the Kurdistan Regional Government undertook a referendum to become independent.

So while one suggestion appears plausible, the other seems outlandish.
As for attacking Iran, the last Iraqi leader who was fooled by the west into doing this is Saddam. Didn't end too well for him, did it? I'd suggest not to repeat his mistakes over and over again, especially since Iraq is even less in a position to do so, no matter what the Americans tell you.
And when I mention Saddam's heaviest historic mistake, I mean mostly the fact that he never understood the exact reason of why the west was supporting him in his aggression against Iran. Contrary to a widespread belief, the answer is not that the west sought to weaken both parties. No, they were actually hoping that Saddam would manage to do their dirty work and overthrow the Islamic Republic. However, they never viewed him as anything other than a disposable tool, a moron they would remove as soon as necessary. Because, entering a pact with the devil, so to say, makes one dependent on and vulnerable to the latter. Such as Iraq with its mountains of debt towards PGCC monarchies at the end of the war Saddam imposed on Iran. Which led to the invasion of Kuwait, a trap which in turn triggered the destruction of Iraq and the hands of the US regime.
Lesson for our Iraqi brothers: do not trust the US regime. Do not believe them when they turn reality upside down by trying to demonize Iran as a supposed "threat" to you - when in fact they and their zionist masters are the main threat to the Iraqi nation's very existence; do not listen to them when they offer you assistance for initiating completely unwarranted hostilities against Iran.
