But as Iran's neighbor Turkey is more powerful, and there are 300 million Arabs to 75 million Iranians, and one-third of all Iranians are Azeri, Baluch, Arab and Kurd, why is this our problem?
We may have to deal militarily with Syria, too, says Rubio. With Turkey and the Arab League, we should "create a safe haven" for the opposition to Bashar Assad and consider equipping it with weapons.
But if we have survived Bashar and were allied with his more ruthless father during Desert Storm, why is his departure vital?
Oddly for a man under consideration for vice president, Rubio is positively insulting to Vladimir Putin, who will be leading the world's largest nation and second-largest nuclear power for the next six years.
"Putin might talk tough," says Rubio, "but he knows he is weak. Everywhere he looks, he sees threats to his rule, real and imagined. And so he uses state-owned media to preach paranoia and anti-Western sentiments to Russians."
We should ignore him, says Rubio, and move ahead with "the continued enlargement of NATO."
Now, as NATO already encompasses Poland and the Baltic states, what additional nations would Rubio bring in under our nuclear umbrella?
It is the George W. Bush idea of bringing Ukraine and Georgia into NATO, which would commit us to war with Russia over who owns the Crimean Peninsula and who is sovereign in Abkhazia and South Ossetia.
What vital U.S. interest is wrapped up in these regions that most Americans could not find on a map?
All belonged to the old Soviet Union. Not even the toughest U.S. Cold War presidents dreamed of going to war over them.
"Faced with historic deficits and a dangerous national debt, there has been increasing talk of reducing our foreign aid budget," says Rubio.
Yes, and some of that talk has come from Mitt.
But Rubio is having none of it.
"Foreign aid is a very cost-effective way not only to export our values, but to advance our security and economic interests."
Yet, with $5 trillion in deficits in one Obama term and a national debt larger than our gross national product, does it make sense to borrow tens of billions annually from China to send to Third World regimes that vote against us and with China in the United Nations?
Is Marco Rubio tomorrow's man. Or is he just an echo of yesterday?
