Is there any end in sight for the Russia/Ukraine war? Not according to German diplomat and Munich Security Conference head Christoph Heusgen, who spoke to Ian Bremmer on GZERO World.

"I believe this will go on for some time. Putin is not ready to give in and Zelensky will continue to fight."

With both sides dug in, the only certainty is that more people will die as winter descends on the region. And while Western Europe's resolve for Kyiv's cause remains strong, there may be some cracks beginning to show.
