The US Congress is unable to vote on a new envelope for Ukraine and Israel. A bill supposed to approve funds for these two warring allied countries has nevertheless been fiercely negotiated for months.

The Democratic general staff, in charge in the Senate, is preparing a series of alternative scenarios "after the failure expected on Wednesday", a source said. Failure to adopt new funds would be a huge disappointment for Ukraine, whose counter-offensive in the summer largely failed. It would also constitute a significant setback for Joe Biden against his European partners, who approved on February 1 an extension of 50 billion euros for kyiv.
