He maybe referring to those currently living, because if Lyndon Baines Johnson was alive I think he'd give Bomber Trump a run for his money for that highly undesirable title.
Anyhoo, Bomber Trump is giving Israel $705 million to Israel for missile defence.
The US gives Israel record military aid annually, and that aid is always growing. One of the biggest avenues for growth is funding for Israel’s missile defense systems. This year, Congress has committed $705 million to this scheme, up from just about $550 million last year.

But at the same time, Israel is making 350 Palestinians homeless by destroying the village of Umm al-Hiran, and the villagers claim there are no plans to permanently rehome them.
Israel has announced plans to demolish the entire Bedouin village of Umm al-Hiran in the southern Naqab region in April.
If enacted, Israel will force 350 Palestinians into homelessness.
...Israel plans to transfer the villagers to the nearby Bedouin town of Hura for two years, until permanent residence is built, the publication Arab48 reported.
Two Israeli government organizations, the National Planning and Building Council and the Bedouin resettlement authority in the Negev, are pushing to strike a deal with community members by allocating them a share of the land. But community leaders said that no agreement has been made with either Israeli body.

Umm al-Hiran lies in the Naqab region of Southern Israel, and is neither in the Gaza Strip nor in the West Bank. But according to the article, the Bedouin who currently occupy the village lived nearby until the Nakba, after when in 1956 the Israelis forced them to move there promising them decent alternative accommodation. But as you can guess, those promises from Israel were never honoured, and the village is currently unrecognised by Israel and as a consequence receives hardly any basic services such as water and electricity. Thus these Bedouin, although they do not live in the Gaza Strip or the West Bank are Palestinian.
This is ethnic cleansing in slow motion, so that nobody in the world notices.
And Bomber Trump boasts that nobody loves and is more loyal to Israel than him.
