Research from Ivan Katchanovski who is a political scientist at the University of Ottawa shows that Ukraine is US client state sui generis since Maidan & is used for proxy war:

"Since 2015, the CIA has spent tens of millions of dollars to transform Ukraine’s Soviet-formed services into potent allies against Moscow, officials said. The agency has provided Ukraine with advanced surveillance systems, trained recruits at sites in Ukraine as well as the United States, built new headquarters for departments in Ukraine’s military intelligence agency, and shared intelligence on a scale that would have been unimaginable before Russia illegally annexed Crimea and fomented a separatist war in eastern Ukraine. The CIA maintains a significant presence in Kyiv, officials said...

In reality, they represent capabilities that Ukraine’s spy agencies have developed over nearly a decade — since Russia first seized Ukrainian territory in 2014 — a period during which the services also forged deep new bonds with the CIA.

The missions have involved elite teams of Ukrainian operatives drawn from directorates that were formed, trained and equipped in close partnership with the CIA, according to current and former Ukrainian and U.S. officials.

The CIA-Ukraine collaboration took root in the aftermath of 2014 political protests that prompted Ukraine’s pro-Russian President Viktor Yanukovych to flee the country, followed by Russia’s annexation of Crimea and its arming of separatists in the eastern regions of Donetsk and Luhansk.

To manage that security risk, the CIA worked with the SBU to create an entirely new directorate, officials said, one that would focus on so-called “active measures” operations against Russia and be insulated from other SBU departments.

The new unit was prosaically dubbed the “Fifth Directorate” to distinguish it from the four long-standing units of the SBU. A sixth directorate has since been added, officials said, to work with Britain’s MI6 spy agency.

Over one three-year stretch, at least half a dozen Russian operatives, high-ranking separatist commanders or collaborators were killed in violence that was often attributed to internal score-settling but in reality was the work of the SBU, Ukraine officials said.

Among those killed was Yevgeny Zhilin, the leader of a pro-Russian militant group in eastern Ukraine, who was gunned down in 2016 in a Moscow restaurant. A year later, a rebel commander known as ‘Givi’ was killed in Donetsk as part of an operation in which a woman who accused him of rape was enlisted to plant a bomb at his side, according to a former official involved in the mission.

Even while helping to build the SBU’s new directorate, the CIA embarked on a far more ambitious project with Ukraine’s military intelligence service.

“We calculated that GUR was a smaller and more nimble organization where we could have more impact,” said a former U.S. intelligence official who worked in Ukraine. “GUR was our little baby. We gave them all new equipment and training.”

From 2015 on, the CIA embarked on such an extensive transformation of the GUR that within several years “we had kind of rebuilt it from scratch,” the former U.S. intelligence official said. One of the main architects of the effort, who served as CIA station chief in Kyiv, now runs the Ukraine Task Force at CIA headquarters.

The GUR began recruiting operatives for its own new active measures department, officials said. At sites in Ukraine and, later, the United States, GUR operatives were trained on skills ranging from clandestine maneuvers behind enemy lines to weapons platforms and explosives. U.S. officials said the training was aimed at helping Ukrainian operatives protect themselves in dangerous Russian-controlled environments rather than inflicting harm on Russian targets.

Some of the GUR’s newest recruits were transfers from the SBU, officials said, drawn to a rival service flush with new authorities and resources. Among them was Vasyl Burba, who had managed SBU Fifth Directorate operations before joining the GUR and serving as agency director from 2016 to 2020. Burba became such a close ally of the CIA — and perceived Moscow target — that when he was forced from his job after President Volodymyr Zelensky’s election the agency provided him an armored vehicle, officials said. Burba declined to comment for this article.

The CIA helped the GUR acquire state-of-the-art surveillance and electronic eavesdropping systems, officials said. They included mobile equipment that could be placed along Russian-controlled lines in eastern Ukraine, but also software tools used to exploit the cellphones of Kremlin officials visiting occupied territory from Moscow. Ukrainian officers operated the systems, officials said, but everything gleaned was shared with the Americans.

Concerned that the GUR’s aging facilities were likely compromised by Russian intelligence, the CIA paid for new headquarters buildings for the GUR’s “spetsnaz” paramilitary division and a separate directorate responsible for electronic espionage.

The new capabilities were transformative, officials said.

“In one day we could intercept 250,000 to 300,000 separate communications” from Russian military and FSB units, said a former senior GUR official. “There was so much information that we couldn’t manage it ourselves.”

Troves of data were relayed through the new CIA-built facility back to Washington, where they were scrutinized by CIA and NSA analysts, officials said.

“We were giving them the ability — through us — to collect on” Russian targets, the former GUR official said. Asked about the magnitude of the CIA investments, the official said: “It was millions of dollars.”

In time, the GUR had also developed networks of sources in Russia’s security apparatus, including the FSB unit responsible for operations in Ukraine. In a measure of U.S.-Ukraine trust, officials said, the CIA was permitted to have direct contact with agents recruited and run by Ukrainian intelligence.

...The SBU launched a second strike on the bridge nine months later using naval drones that were developed as part of a top secret operation involving the CIA and other Western intelligence services...

Ukraine officials denied that either agency was directly involved in the September 2022 attack on the Nord Stream 2 pipeline in the Baltic Sea, though U.S. and other Western intelligence agencies have concluded that Ukraine was linked to the plot.

GUR has also ventured into assassinations, officials said. Security officials said that no major operation by the SBU or GUR proceeds without clearance — tacit or otherwise — from Zelensky.

Officials acknowledged in recent interviews in Kyiv, however, that those denials were false. They confirmed that the SBU planned and executed the operation, and said that while Dugin may have been the principal target, his daughter — also a vocal supporter of the invasion — was no innocent victim."
