Recent events have shown how personal international relations can get, with the news that President Barack Obama has canceled his meeting with Russian President Vladimir Putin. The cancelation is widely believed to stem from personal frustration between the two leaders.
It should come as no surprise that even something as important as international politics is subject to the same awkwardness as family get-togethers, with splits, insults and occasionally just awkward moments.
Here's a list of some awkward moments between world leaders.
This is one of the few cases on the list where the aforementioned awkwardness stems from simple dislike of each other.
Every time Barack Obama and Vladimir Putin get together, the tension is palpable, with bored looks from Putin and discontent looks from Obama providing plenty of fodder for the cameras.
Whether discussing Edward Snowden or the Syrian crisis, it's clear that these two won't be throwing surprise birthday parties for each other anytime soon.
You can thank alcohol for saving these allies in World War II — that might be a little dramatic — but a few dozen bottles of vodka and Caspian red wine can be thanked for easing tensions between Soviet Premier Joseph Stalin and British Prime Minister Winston Churchill.
At a meeting in Moscow in 1942, the two leaders were getting along poorly at public events throughout the day. Many thought the trip a disaster.
But later that night, Sir Alexander — accompanying Churchill on his visit — recalled being summoned to a meeting room late at night where "I found Winston and Stalin, and Molotov who had joined them, sitting with a heavily laden board between them: food of all kinds crowned by a sucking (sic) pig, and innumerable bottles. What Stalin made me drink seemed pretty savage: Winston, who by that time was complaining of a slight headache, seemed wisely to be confining himself to a comparatively innocuous effervescent Caucasian red wine."
This was a diplomatic meeting that would give "Saturday Night Live" all the material it could have asked for. President George Bush was pictured holding the hand of Saudi King Abdullah while walking through the White House gardens.
The stated reason for the hand holding was to show friendship and solidarity while accommodating Saudi customs. However, some have speculated that it was a way for Bush to keep the Saudi king from walking out of a tense meeting in the wake of Sept. 11.
As the world looked on helplessly, the leaders of the G8 countries posed for a "family picture" at the 2009 G8 Economic Summit.
As the presidents and prime ministers gathered, Italian Prime Minister Silvio Berlusconi grabbed the wrist of Japanese Prime Minister Taro Aso to examine his cufflinks.
Soon the French president and Russian president joined in the ogling of the Japanese wrist decor, all the while German Prime Minister Angela Merkel and other leaders looked at the cameras awkwardly.
Interesting cufflinks at a G8 summit wouldn't prove to be the only time the flamboyant Italian prime minister, Silvio Berlusconi, would leave his German counterpart, Angela Merkel, looking awkwardly at the cameras.
Berlusconi would do it again at a 2009 NATO summit, where instead of walking from his car down a carpet to greet Merkel, he wildly gestured that he needed to take a call and would spend the next three minutes on the phone while Merkel looked on with disbelief and awkward smiles.
Given Russia's recent crackdown on government dissenters at home, it shouldn't come as a surprise when Russian President Putin is greeted with protests when he goes abroad. But that's not the awkward part of this international incident — nearly every world leader will be the victim of protesters during a foreign visit. It's Putin's reaction to this particular protest that truly makes it an awkward moment for all involved.
Upon arriving in Germany and greeting Angela Merkel, Putin and Merkel would find their entourage rushed by a group of topless protesters, who were voicing their opposition to the Russian imprisonment of a female punk-band.
While Merkel looked on with discontent trying to ignore the situation, Putin's face was much more amusing. He would later say of the incident, "Regarding this performance, I liked it."
At a state banquet at Buckingham Palace in 2011, President Obama would make the tragic mistake of pausing momentarily as he gave a toast to the queen.
The royal band took the pause as a sign to commence playing "God Save the Queen." Obama continued his toast as the band played, downing his drink in the middle of the song.
The crowd stood there confused for the rest of the song, before toasting at the end of the song.
For 130 years it was tradition for the outgoing president to join the incoming president on a car — or carriage — ride on the route to the inauguration.
Under the best of circumstances, it could be a nice drive; under the worst, it could be openly hostile.
But few were as plain awkward as the last time it would happen, when President Franklin D. Roosevelt gave outgoing President Herbert Hoover a ride in his open-top car. The two sat in silence, casting less than amiable glances toward the crowd as they passed.
The two had developed a strong dislike of each other in the months leading up to the inauguration, and the ride proved so awkward that the tradition was done away with after the sulking car ride.
In 1991, Queen Elizabeth II joined President George H.W. Bush to give a speech on the White House lawn.
However, a White House staffer forgot to lower the microphones to accommodate the queen's height.
Nevertheless, the speech had to go on, and so the president and the queen stood side-by-side on the White House lawn as she gave the speech, her face hidden from view the entire time.
