I don't think so.

~8 years ago Trump did the same exact thing. He traveled to the Arabian peninsula to meet with the Arab dictators that are renting the land on the southern shores of the Persian Gulf.
The mainstream media aka the mouthpieces advertised it largely, talking about how he milked the Arab dictators (aka cashcows as Trump loves to refer to them) for trillions of dollars.
But in reality a tiny fraction of it was met.

The situation this time is even worse.
Trump planned this travel for 100 days trying to get some "wins" then enter Arabia as a winner and milk these dictators better. But instead he only experienced failures and entered Arabia defeated. As a failure in everything.
- No 24-hour peace in Ukraine
- No peace in Gaza
- Isolated USA
- No annexation of Canada
- No annexation of Greenland
- No annexation of Panama and its canal
- Defeated in the proxy war against Pakistan (as PAF dominated the Western air technology)
- Defeated in the direct war against Yemen
- Failed in the tariff war against China
- and a lot more

On the other hand, the Arab dictators' economic situation is worse than ~8 years ago. They are facing an economic crisis and they no longer have the same amount of money to invest in the US. What they had is already in the US and they've wasted a lot of it in the past years in US regime's proxy war against Yemen! Their budgets are also set with a higher oil price ($80-$90) so they'll face a massive deficit because of that as well (oil is currently $60). That is on top of other crisis they are facing (eg. the employment crisis in Saudi usurped Arabia).

The only conclusion we can make is that like last time, the Arab dictators who are renting the land around the Persian Gulf are going to promise Trump trillion but fulfill an even smaller percentage compared to last time...
