Why did Trump give $350 Billion to Saudi Arabia?

Donald Trump Just signed an arms deal with Saudi Arabia worth $110 billion dollars and set to increase to $350 billion over the next ten years. Why on Earth would someone who vowed to stomp out “Radical Islamic Terrorism” fund the leading sponsor of it?
​
​Well it comes down to the fact that Israel and the United States has long planned for the overthrowing of not only Syria’s government, but Iran as well. With Donald Trump proving to be the “most pro-Israel president ever” it’s no wonder that he is shelling out cash to Israel’s proxy state. Israel would never attack Iran straight on but using Saudi Arabia and its terrorist armies seems a very likely scenario. And this has even come from their very own mouth, not just mine.
