Despite Obama's repeated claims that he has ended the Iraq war -- or at least America's participation in it -- the fact remains that America's role there was in the process of winding down at the end of the Bush presidency. The United States and Iraq had already worked out a troop-withdrawal schedule as Obama was preparing to take office and to a large degree, it was the Iraqi government that accelerated that process.

In effect, the Iraq war that Bush handed off to Obama was all but over, U.S. troops were being redeployed, Al Qaeda attacks had plummeted, the Nouri al-Maliki government was arguably more secure, and Iraqi military forces were fully in charge, with U.S. backup as needed.

Afghanistan now looms as the greatest national-security test of Obama's presidency. U.S. forces liberated Afghans from the Taliban during the Bush era, and he installed a friendly pro-Western government. But the Taliban have come roaring back since Obama came into office and he is, for all intents and purposes, pursuing Bush's existing military policies to stabilize that nation by adding more troops to the fight.

When the war in Iraq was going badly, Bush gave Gen. David Petraeus the funds and forces he needed to defeat Al Qaeda. Now Obama faces the same decision in Afghanistan that Bush faced in Iraq: whether to agree to Gen. Stanley McChrystal's request for up to 40,000 more troops or else lose the war.

Petraeus and the rest of the Pentagon's top brass have endorsed the request, but Obama has publicly expressed his doubts about a wider war and has delayed a decision until he can complete a further review.

Earlier this year, Obama said that his Afghan war strategy would be "stronger and smarter." Last week, doubts were beginning to creep into his mind. "Are we pursuing the right strategy?" he asked on NBC's "Meet the Press."

Elsewhere on his global agenda, things are looking more dangerous than ever since taking office. North Korea has grown far more belligerent and dangerous, firing off missiles that threaten its neighbors and possibly the United States. Iran continues apace with its nuclear ambitions and its short-range and midrange missile program. Russia scored a major victory by getting Obama to kill the anti-missile installations in Poland and the Czech Republic that it opposed.

Indeed, Russian Prime Minister Vladimir Putin may be getting more than he hoped from Obama, who has proposed slashing Ronald Reagan's visionary Strategic Defense Initiative program by 15 percent.

Obama talked big in his U.N. speech, but the foreign-policy threats that now loom on the horizon are growing bigger.
