Is that what they're pledging as an appetizer while they bring a serious proposal to help? Otherwise why even bother?
Instead of dismissing allies' contributions, perhaps consider that effective support for Ukraine requires many nations doing what they can within their means (and their GDP). The UK consistently steps up, and every contribution strengthens Ukraine's position."
Furthermore, the $2.85 billion pledge represents approximately 5% of the UK's annual defense budget (which is roughly £50-55 billion).
Your comments are not very constructive or informed about the realities of international aid. When measured proportionally against national capabilities, this is a substantial commitment that will fund critical defense systems Ukraine needs.
Dismissing allies' contributions doesn't help Ukraine - recognizing and encouraging sustained support does.
