President Donald Trump has literally drawn a line in the Arabian sand for the rogue, terrorist financing state of Iran.

“While you have been constructing the world’s tallest skyscrapers in Jeddah and Dubai, Tehran’s 1979 landmarks are collapsing into rubble and dust. They had it going for a while under a much different system. Those buildings are largely falling apart, falling down, while you are building some of the world’s biggest and most incredible infrastructure projects, buildings, all sorts of things we’re building that nobody has ever even seen before,” he said in a speech in Saudi Arabia on Tuesday.

“Iran’s decades of neglect and mismanagement have left the country plagued by rolling blackouts, lasting four hours a day, all the time. Your skill has turned dry deserts into farmland. Iran’s leaders have turned theirs into dry deserts, as their corrupt water mafia—let’s call it the water mafia—causes droughts and empty riverbeds. They get rich but don’t let the people have any of it,” the president said.

“Then, of course, there is the key difference at the root of it all. While the Arab states are focused on becoming pillars of regional stability and world commerce, Iran’s leaders have focused on stealing their nation’s wealth to fund terror and bloodshed abroad. Most tragically of all, they have dragged down an entire region with them. Countless lives were lost, the reigning effort to prop up a crumbling regime in Syria—look at what happened with Syria. In Lebanon, their proxies have pillaged the hopes of a nation whose capital, Beirut, was once called the Paris of the Middle East. Can you imagine? All this misery, and so much more, was entirely avoidable—absolutely avoidable. Smart people knew that,” he said.

Trump said he was not only there to “condemn the past chaos of Iran’s leaders but to offer them a new path, a much better path toward a far better and more hopeful future.”

“I have never believed in having permanent enemies,” the president said. “I want to make a deal with Iran. If I can, we will make the region and your world a safer place.”

“But if Iran’s leadership rejects this olive branch and continues to attack their major diplomatic neighbors, we will have no choice but to inflict maximum pressure, drive Iranian exports to zero, like I did before,” President Trump said.

“We will take all action required to stop the regime from having a nuclear weapon. Iran will never have a nuclear weapon. That’s my promise,” he said.
