Given the evidence shown, it's clear that this was not an Israeli missile or bomb- the damage pattern is wrong and too minor. In one video you can see a rocket launch exploding, then the blast below at the hospital. Most nations are telling their people to get the "H" out of the area. Russia will stay out- no resources to spare. China has resources, but they will lose too much economically to get involved. Both know what happened at the hospital and are certain to have told their friends and allies as much. Islamic nations are becoming quieter in light of the evidence and the growing belief in it, which matches how these terrorists have always operated firing rockets near schools, hospitals, and population centers knowing any retaliatory strike will kill many innocents. Utter cowards, and now everyone can see that- except Iran. They are and will remain the wild card here but given the other Arab nations reticence to do anything, they may officially stay out though they have already armed Hezbollah who will get involved to some degree.
Biden's last statement was that they have an agreement to let humanitarian aid into Palestine as soon as the hostages are released, which is a politically and militarily perfect response to the terrorists since it's now clear that they do not care about Palestinians at all, both in starting the conflict and blasting these people's hospital too. Other than Iran everyone seems to want to stay out of it now, and Iran alone can't save Hamas. The posturing and positioning are over, and Hamas holds the key to whether the Palestinians receive aid or not. The bullets are about to fly.
