Fylingdales and Menwith Hill will be the first targets from Russia, not Catterick.
I am more worried about the naval exercises off Ireland which will be a distraction. I think they are more bothered about cutting undersea cables, disabling communications with allies before invading Ukraine. Germany seem to appease Putin for some reason, no doubt energy related.
If we let them into Ukraine unopposed, where next, Poland? If only we had a previous megalomaniac from history we could reference! The West need to show unity and strength otherwise Europe will look like easy pickings over time (which in truth it probably is).
