“Russia can definitely be defeated, and Ukraine has already shown how to do it,” Defense Minister Alexei Reznikov said in a speech to the Atlantic Council on Tuesday.

The article says that Western officials are concerned that Kyiv, buoyed by arms deliveries, may launch a counteroffensive too soon.

The Pentagon is also not sure that US own stockpiles will not be depleted in the coming months.

“Ukraine is faced with a choice of strategy: how should it use its deadly new capabilities: concentrate firepower for defense in the east or attack ... Kherson, which is held by the Russians but is seen as vulnerable,” the author writes.

According to him, some Western officials fear that the Ukrainian Armed Forces are not ready for a major counteroffensive in the Kherson region.

To which, as stated in the article, Ukraine objects that it has avoided hasty or risky maneuvers using new weapons and will not act prematurely.
