If Israel were to have 55% of the Mandated territory it would have all of Judea and Samaria and 27% of Jordan. You either never knew or failed to remember that about 78% of the territory given to the UK to administer in their Mandate was given to form Jordan. It was the Arabs that refused to form their state. When a nation wages an offensive war they may lose territory when they lose. Just look at the result of WWII.
