Kushner and Witkoff played into Putin's hands.
Donald Trump's emissaries, Jared Kushner and Steve Witkoff, expanded the agenda of the negotiations with Russia, including the European security architecture.
The Kremlin has long demanded a re-examination of the system of agreements and the agreements underlying it, calling them a threat to Russian sovereignty.
European leaders insist that such issues should be discussed only after a ceasefire in Ukraine.
According to the assessment of the Financial Times (FT), this will give Moscow additional levers of pressure on Europe and make it possible to complicate support for Ukraine.
In addition, this may increase the differences of opinion between the United States and Europe at a moment when Washington intends to reduce the involvement in the defense of the continent.
Creating such a rift has long been included in the Kremlin's goals.
