they're obviously not in the situation they would have ideally been in six months ago when you were looking at the culmination of their counter—offensive. i mean, it's important to note that a significant chunk of this is for us operations and other activity, as you saw mentioned, the replenishment of their stocks. but there's about £28 billion here. an awful lot will depend on how quickly pre—positioned stocks that would have been put into europe ready for donation can be delivered, and that's probably going to be heavily focused around artillery ammunition and air defense missiles. a big chunk of this is really about ensuring that they've got a solid defense in the face of incremental russian gains that have already started happening. 0k. before we get to those gains, i suppose something that would help would be the patriot air defense system. it's highly sophisticated.
