President Trump said Monday that peace negotiations with the Taliban are “dead as far as I’m concerned” after the terrorist group claimed responsibility for a bombing in Afghanistan that killed an American service member.

Democrats are roasting President Trump this week for his cancellation of a planned summit with Taliban leaders whose aim was to finalize a peace deal for Afghanistan. Presidential candidate Amy Klobuchar said Trump was conducting foreign policy as if it were “a game show.”

But the bottom line about Trump’s decision is that it was correct.

This Abridge News topic aggregates four unique arguments on different sides of the debate. Here are the quick facts to get you started:

THE QUICK FACTS

After the U.S. invasion of Iraq in 2003 turned into a mess that led to an immense loss of life and years of violent havoc in the Middle East, the war's backers flippantly declared that "everyone" agreed on the war. The invasion's evolving justifications—Saddam's supposed amassing of "weapons of mass destruction" to his alleged ties to Al-Qaeda—were overblown, but if everyone was in agreement then who could possibly second-guess the military effort?

President Trump returns from his foray into Saudi Arabia, Israel, the Vatican, then with EU leaders. He demonstrated a unique foreign policy vision, one unpopular with many elites but welcome to voters.

With fighting intensifying in eastern Ukraine and the White House weighing whether to send arms to bolster the government’s forces, Western leaders embarked on a broad diplomatic effort on Thursday aimed at ending a conflict that has strained relations with Russia.

Yet, the prospects of achieving a new peace plan remained clouded by deep suspicions of Moscow, born of its history of dissembling about its intentions and operations in Ukraine, Western diplomats and Ukrainian officials said.

European leaders scrambled Thursday to try and forge a diplomatic deal to end fighting in eastern Ukraine, in an apparent bid to head off U.S. consideration of lethal military aid for the Ukrainian government in its war against Russian-backed separatists.

At the same time, a bipartisan call in Congress for the U.S. to arm Ukraine was only growing, with lawmakers saying the military aid "is past due."

"We can't just stand by and let them be slaughtered by superior weapons," Sen. John McCain, R-Ariz., chairman of the Senate Armed Services Committee, said Thursday.

Diplomatic efforts are under way to end renewed fighting in eastern Ukraine.

French President Francois Hollande and German Chancellor Angela Merkel held urgent talks in the capital Kiev, presenting a new peace initiative.

US Secretary of State John Kerry, who is also in Kiev, said the US wanted a diplomatic solution, but would not close its eyes to Russian aggression.

Fighting between Ukrainian forces and pro-Russian rebels has killed nearly 5,400 people since April, the UN says.
