When will the "allies" figure out Uncle Sam isn't worth the candle?

The current Ukraine situation was completely avoidable. 

Ukraine and its separatist regions negotiated the Minsk agreement seven years ago, in negotiations refereed by Russia, France, and Germany. It stipulated a degree of autonomy for the rebel provinces as a condition for the cessation of hostilities.

Unfortunately, although the deal was approved by the UN, it fell afoul of the folks who had engineered the coup of 2014 - the US government. 

And here we are!

The World Cop who worked tirelessly to prevent peace in Ukraine now leads the world in accusing Russia of an unprovoked attack on its neighbour! It has rallied its allies, also known as colonies, satrapies, stooges, dependencies, or flunkies, NATO and the EU, to stand strong against Russian aggression.

The European allies get to stand strong in Europe. They will make serious sacrifices. Double or treble heating bills for the average citizen. Billions of euros for the refugee wave soon to crash their borders, perhaps as large as the wave that came their way due to America's previous adventures in Afghanistan, Iraq, and Syria. 

In the event this little war goes sideways, as wars have been known to do, Europe will be in the soup.

America, which has driven this conflict since the '90s, is leading the charge against Russian aggression. It is leading with the declaration of sanctions from hell, the mother of all sanctions, etc.

It is leading from the other side of the Atlantic, thousands of miles away from the hot war it precipitated.

While the European allies are making sacrifices, the Americans are willing to sell unlimited billions in US military hardware to the EU and our NATO allies, and of course, to the Ukrainians. Nothing like a war to goose profits at Raytheon et al.

The Americans will also pitch in by selling LNG to the allies to replace the Russian gas Putin now is free to sell elsewhere. The price will be several orders of magnitude higher than the Russian gas now sanctioned, but that's due to the free market, not US policy.

It's only coincidence that US corporations profit massively while the allies make sacrifices to preserve America's role as World Cop.

What I find utterly baffling, is why the allies refuse see that the American Emperor is buck naked?

If Uncle Sam were a proper hegemon, he'd be doing more than sanctions. Sadly, at least for the American Empire, that's all he's got.

Sooner or later,  our allies are gonna figure out they're the only thing keeping the empire afloat, and then the jig will be up.
