How long will the mellowing out take and how many Israeli civilians will die during that? Half of the people in Gaza were born after Hamas came into power.
Ireland is a viable economy on it's own. The average education level in Gaza is abysmal, there are no resources, little farmable land,... There is no perceivable way for Gaza to function as a independent part of Palestine independent of either Israel or Egypt. So what's the plan here?
Egypt wants nothing to do with Gaza anymore. I don't think anyone in Israel would support incorporating Gaza into Israel and grant citizenship to it's inhabitants.
Just closing the border and largely keeping out there is what Israel did the last two decades and that is exactly what ended up in an unprecedented terror attack on Israeli civilians.
A lot of other European countries depended on Russian gas. Some even more than Germany. That's not the main reason for the slow recovery from COVID and the energy crisis. Germany let a lot of it's infrastructure rot and is now facing the consequences. Additionally there are ideological debt restrictions in place, hindering the government to start a stimulus program, while a lot of other countries are doing exactly that.
