In a move to hanstring Ukraine and deliver the soft under belly to Putin"

The US has cut off intelligence-sharing with Kyiv in a move that could seriously hamper the Ukrainian military’s ability to target Russian forces, according to officials familiar with the matter.
The move follows the decision on Monday by the Trump administration to suspend military aid deliveries to Ukraine and comes after a dramatic breakdown in relations between the US president and Ukraine’s Volodymyr Zelenskyy.
US intelligence co-operation has been essential for Ukraine’s ability to identify and strike Russian military targets.
Three officials familiar with the decision confirmed that Washington had frozen intelligence channels with Kyiv.
While the US has also formally blocked its allies from sharing US intelligence with Ukraine, two officials said that recipients with assets inside the country were likely to continue passing on relevant intelligence to Kyiv. But that would not apply to time-sensitive and high-value intelligence, such as that needed for Ukraine to conduct precision strikes on moveable Russian targets.
