No, that's a logical fallacy. I can be against something obviously wrong without offering an alternative action. In fact, this is a case of "something needs to be done, this is something, so this must be done". Wrong. Doing nothing—not starving Gaza—was also an option; one that the Israeli government decided against. They are responsible for the current situation.

Pretty sure the people responsible are the ones hijacking aid trucks and causing security problems in distribution areas. Hamas has a long history of misdirecting aid from the Gazan population; stealing, oppressing, punishing, exploiting, and that's from before the war as commonly reported by UN sources and humanitarian groups over the years.
