Who has said that the UK military can’t sustain these casualties?
I saw the piece as highlighting that the UK has suffered 240 dead (Rest in Peace) and many hundreds wounded in Iraq and Afghanistan (the only other Western Country after the US to be willing to shoulder these sorts of casualties). There has only been 1 year that Britain hasn’t lost troops in combat since 1968. You can’t exactly call the UK casualty shy.
Just a correction on previous post: Britain has only had one year in which it hasn’t lost troops in combat since WW2. I believe that year was 1968. I muddled my sentence up.
