` :::Scholar don't mention an ``invasion of Israel`` but an ``invasion of Palestine``. That can neutralize this in writing that ``they intervened in Palestine`` or ``sent expeditionnary forces to Palestine``. :::The reasons are that their intentions were different for each of them. :::When we looked at the events, it can be understood  :::* Arab Legion, the stronger, didn't enter at any stage of the war in territories allocated to Israel (but were attacked by Israeli on terriroties allocated to the Arab states) ; his will was to take control of these territories but not attacking Israelis. :::* Iraki tried to enter Israel but failed and after 3 days went back and never again tried to attack Israel :::* Syria took an area of 2 x 3 km but never went further (technically, they invaded [a small part of] Israel :::* Lebanon didn't intervene at all whereas it declared war through the Arab League :::* Egypt first attacked kibboutzim that were in the territories that were allocated to the Arab states and never really succeeded in ``invading Israel`` whereas they technically did so at some places and that they blockaded Negev settlements. :::But in any cases, scholars refer to the ``invasion of Palestine``.   `
