We are at war with ISIL in Syria and Iraq. Homeland Security considers America jihadists that return from the middle east to be enemies and "major threats".
But what about when they aren't from the United States? What about if they go to Ukraine instead?

MARIUPOL, Ukraine — Just an hour’s drive from this city under siege, at an old resort on the Azov Sea that’s now a military base, militants from Chechnya—veterans of the jihad in their own lands and, more recently, in Syria—now serve in what’s called the Sheikh Mansur Battalion. Some of them say they have trained, at least, in the Middle East with fighters for the so-called Islamic State, or ISIS...
Over the past year, dozens of Chechen fighters have come across Ukraine’s border, some legally, some illegally, and connected in Donbas with the Right Sector, a far-right-wing militia. The two groups, with two battalions, have little in common, but they share an enemy and they share this base.

Since we oppose Russian intervention in Ukraine, that sort of complicates the situation. We have U.S. troops in Ukraine right now training Ukrainian soldiers to fight Russian-backed rebels. These soldiers often fight right alongside the Ukrainian army (and sometimes against it).
After all, we oppose Russian military aggression...sometimes. Sometimes not.

The White House on Thursday said it was closely monitoring reports that Russia is carrying out military operations in Syria, warning such actions, if confirmed, would be "destabilising and counter-productive."
...
The White House said, however, that it would welcome Russia's involvement in the international coalition established to counter Islamic State and in diplomatic efforts to end the brutal civil war.

So Russian support for the Assad government when it is fighting ISIS is "destabilising and counter-productive", however, Russian military actions against ISIS in Syria is "welcome". So I guess whether Russia is a frenemy or not a frenemy depends on how you look at it.
But is Russia bombing ISIS?

Idlib province, where the Russians were bombing, isn't under ISIS control. Idlib is under control of the Army of Conquest, which is made up of various jihadist groups, mainly Ahrar ash-Sham and al-Nusra Front, the Al-Qaeda branch in Syria.
You see, Russia is working with the Assad government, and to the Assad government all rebel groups are equal.

One report has even alleged that Russian pilots are gearing up to fly missions alongside the Syrian air force, dropping bombs not just on ISIS but on anti-Assad rebels who may or may not be aligned with the United States or its regional allies.

So 'hurray' for Russia bombing ISIS and 'boo' for when they bomb our Syrian allies.

Speaking of bombing our allies, no one does it better than our NATO ally Turkey.

A senior US official has accused Turkey of pulling a bait-and-switch by using a recent anti-Islamic State agreement with the US as a "hook" to attack the Kurdish PKK in northern Iraq, The Wall Street Journal reports.

The Kurds have been the most effective fighting force against ISIS. PKK volunteers have come from Turkey by the thousands to fight in Syria and Iraq. Many of them have joined the PKK affiliated group in Syria, the Kurdish People's Protection Units (YPG), which Turkey has also attacked.
So who is America's ally here: Turkey, our NATO ally? Or the Kurds who have sacrificed so much to defeat ISIS?
I'll give you a hint: this wouldn't be the first time we've betrayed the Kurds.

Also, whether an jihadist is a frenemy or not a frenemy depends on what location they are fighting in and who they are fighting.
For example, remember al-Qaeda? You know, the guys who did 9/11?
Well, it seems that whether we want to kill them or arm them depends on the location and situation.

The former commander of U.S. forces in Iraq and Afghanistan has been quietly urging U.S. officials to consider using so-called moderate members of al Qaeda’s Nusra Front to fight ISIS in Syria, four sources familiar with the conversations, including one person who spoke to Petraeus directly, told The Daily Beast...
Petraeus said the U.S. should try “splintering [Al Nusra’s] ranks by offering a credible alternative to those ‘reconcilable’ elements of those organizations.”

"Moderate" al-Qaeda jihadists is quite the concept. It's the kind of idea that only a politician could invent.
In fact, that's exactly what happened. The CIA armed the Mujahideen in the 1980s to fight the Soviets, and some of the Mujahideen went on to form al-Qaeda, while others formed the Taliban.
In fact, a CIA study says that arming radicalized rebels rarely works, but politicians never stop trying.

Syria isn't the only place we are at war with al-Qaeda's enemies. We are also helping to defeat al-Qaeda's enemy in Yemen.

The U.S.-backed war in Yemen has strengthened al Qaeda there, American defense officials concede, posing a serious threat to U.S. security.
Months into the U.S.-supported Saudi intervention in Yemen, fighters linked to al Qaeda in the Arabian Peninsula (AQAP), long considered the terror group’s deadliest franchise, are closing on the southern port city of Aden, according to U.S. officials and local reports.
The land grabs marks the most important gains al Qaeda has made since March, when the Saudi military began its intervention into Yemen. And it gives the group more area to train, plot, and attack U.S. interests. As recently as earlier this month, AQAP called for its supporters to hit the United States, urging lone wolf attackers to strike.

It's not a secret that our allies, Saudi Arabia and UAE, has turned a blind eye to al-Qaeda's rapid growth in Yemen. Nor is it a secret that we are heavily supporting the Saudi-UAE cause.

So let's get down to brass tacks.
Turkey, which has openly supported jihadists in Syria, and that ISIS considers an ally, is bombing the Kurds, the group with a proven track record of fighting ISIS.
Plus, UAE, which helped start ISIS, and which Biden called out, is defeating al-Qaeda's enemy in Yemen.
Plus, we are somewhat allied with Russia against ISIS in Syria, and somewhat allied with ISIS against Russia in Ukraine.

So who does the United States chose as allies in this war: Turkey and UAE.
So is it any wonder that the so-called War on Terror is a stalemate?
