If the relaxation of the pouch is directly tied to the stress/adrenaline response diverting resources elsewhere, which aids in escape, then it's not so easy to optimize to not loose the pouch. Pouch relaxation wouldn't be the genetic trait being selected for or against, flight response would be.

It can be more harmful for the pouch to be relaxed than not on an isolated level, but if that's counteracted by the increased ability to escape due to resource allocation then it would pass on as a "by product" regardless of its individual effect.

There may not be an existing genetic variation which maintains the pouch control during the flight response without compromise on the degree of speed or intensity dedicated to the escape. Evolution can't select for mutations that don't yet exist in the gene pool.

    Not necessarily. Evolution doesn't optimize trait by trait.

    If the flight response leads to overall more reproduction it would naturally pass on regardless of any effect of the loss of pouch control.

    The dropping of the baby wouldn't necessarily be a trait itself, but a side effect of the flight response.

    Literally the opening paragraph of your own link.

    The common definition of Zionism was principally the endorsement of the Jewish people to establish a Jewish national home in Palestine,[1][failed verification] secondarily the claim that due to a lack of self-determination, this territory must be re-established as a Jewish state. Historically, the establishment of a Jewish state has been understood in the Zionist mainstream as establishing and maintaining a Jewish majority.

    How do you "establish a Jewish national home in Palestine", particularly "establishing and maintaining a Jewish majority" in a place where people already live?

    Theodor Herzl is considered the founder of the Zionist movement.

    I wonder what the founder thinks?

    "'national judaism' will make the ancient soil fertile. It seems miraculous. everything natural is miraculous. once the nation that we Zionists are arousing is fully awakened, things will happen swiftly and dynamically. Then the nation will behold it's ancient land beautifully situated on the Mediterranean, with regions of cold, moderate, and warm climate - a land suited for any kind of cultivation, with long dormant natural resources"

    ...

    "Spirit the penniless population across the frontier by denying it employment… Both the process of expropriation and the removal of the poor must be carried out discreetly and circumspectly. "

    ...

    "We shall grant them loans in return for territorial privileges and guarantees. One of the most important concessions they will have to make to us is to allow us to have defensive troops. In the beginning we shall need their permission. Gradually we shall get strong, grant ourselves everything that we need, and be able to defy everyone."

    ...

    Oh...

    I'd like to see the actual proof of Houthis collaboration with ISIS before I believe it.

    ISIS and Houthis aren't aligned basically at all from what I know. ISIS are an extremist Wahhabi group and Houthis are Shia. Houthis are pro-palestine while ISIS has repeatedly attacked Palestine and been supported by Israel.
