World War I started on July 28, 1914, just a month after Austro-Hungarian Archduke Franz Ferdinand and his wife were gunned down on the streets of Sarajevo, Bosnia, by a Serbian nationalist.


The assassination and the subsequent political and military upheavals led to the outbreak of war, which would eventually roil much of the globe.

Three bloody years later, the US would be drawn into the conflict on the side of the Allies, declaring war on the Central Powers on April 6, 1917.

Though the war was sparked by regional tensions, a web of entangling defensive alliances quickly pulled in almost the entire world and hastened the end of the European empires.

In May 2014, Reddit user Srirachachacha shared this map showing how the conflict spread across the world, distinguishing between Allied and Central Powers and their colonies, dominions, and territories.

By the time the war ended, the Russian, Ottoman, Austro-Hungarian, and Prussian Empires had collapsed. The war claimed over 37 million lives, and large swathes of Europe were in ruin.

A little more than two decades later — with the memories of World War I and its resolution still fresh — the world would be on the brink of World War II.

The Colt Model 1911 .45 caliber semiautomatic pistol that John Browning dreamed up more than a century ago remains on of the most beloved sidearms in U.S. military history. Hell, there's a reason why Army Gen. Scott Miller, the top U.S. commander in Afghanistan, still rocks an M1911A1 on his hip despite the fact that the Army no longer issues them to soldiers.

But if scoring one of the Army's remaining M1911s through the Civilian Marksmanship Program isn't enough to satisfy your adoration for the classic sidearm, then Colt has something right up your alley: the Colt Model 1911 'Black Army' pistol.

WASHINGTON (Reuters) - President Donald Trump's withholding of $391 million in military aid to Ukraine was linked to his request that the Ukrainians look into a claim — debunked as a conspiracy theory — about the 2016 U.S. election, a senior presidential aide said on Thursday, the first time the White House acknowledged such a connection.

Trump and administration officials had denied for weeks that they had demanded a "quid pro quo" - a Latin phrase meaning a favor for a favor - for delivering the U.S. aid, a key part of a controversy that has triggered an impeachment inquiry in the House of Representatives against the Republican president.

But Mick Mulvaney, acting White House chief of staff, acknowledged in a briefing with reporters that the U.S. aid — already approved by Congress — was held up partly over Trump's concerns about a Democratic National Committee (DNC) computer server alleged to be in Ukraine.

"I have news for everybody: Get over it. There is going to be political influence in foreign policy," Mulvaney said.

Former Defense Secretary James Mattis decided to take on President Donald Trump's reported assertion that he is "overrated" at the Alfred E. Smith Memorial Foundation Dinner in New York City on Thursday.

"I'm not just an overrated general, I am the greatest — the world's most — overrated," Mattis said at the event, which raises money for charity.

"I'm honored to be considered that by Donald Trump because he also called Meryl Streep an overrated actress," Mattis said. "So I guess I'm the Meryl Streep of generals ... and frankly that sounds pretty good to me. And you do have to admit that between me and Meryl, at least we've had some victories."
