Katz calls Trump's statements a "bold plan, which can allow a large proportion of Gaza's population to move to different places", according to The Times of Israel.
The Gazans should have the freedom to leave and emigrate, just like it usually is around the world, says Katz according to The Jerusalem Post.
He says he has ordered the Israeli defense to prepare regulations for "land border crossings and special arrangements for sea and air travel".
Possible destinations
It sounds like a significant turnaround for Israel's leadership, which for many years has cited security reasons for maintaining a strict blockade against Gaza's two million inhabitants. Strict in- and outbound travel regulations have made it difficult for Palestinians to cross the border, even in acute circumstances such as medical emergencies.
Countries like Canada have occasionally received Palestinian refugees. This contributes to Katz now mentioning it, alongside Ireland, Norway, and Spain, as possible destinations.
On the other hand, it would be more sensitive than ever for Palestinians to leave their homes. Hundreds of thousands of them have barely had time to return, after being displaced within Gaza's borders for months due to the war.
Small opportunities
Moreover, the Palestinians' greatest fear is a new "al-Nakba", the term for the time of Israel's formation when many of the Arab inhabitants of British Palestine were driven out of the new Jewish state. A large proportion of Gaza's inhabitants actually do not originate from Gaza, but from former Arab towns in present-day Israel.
The legal possibilities of making Trump's ideas a reality have also been ruled out in the surrounding world.
