Realistically, the support will stop if there is the impression that this will bring peace to the region - and not only enable those who want to destroy Israel to regain the upper hand and restart their aggression.
As long as Netanyahu is able to point on an enemy that aims to destroy Israel, he will get support for his war. Not because they like the way he does it but because they will never allow Israel to again be faced by superior neighbours poised to destroy it, as experienced in its early years.
My guess is: if Gaza rids itself of Hamas and their goal to destroy Israel, Netanyahu will have a hard time finding war support in Europe.
