Ah, UK celebrated their WWI vet's birthday! (He's got a great grin.)
To Khan--we've learned things and 'improved' diplomatic relations all over the globe, but there's still warring, torture, destruction and man-made suffering. War lords, drug lords, religious wars, the gun trade and weapons industry is doing pretty well....
Maybe you are tired of the doom 'n gloom, and it's comfy to think we're oh so smart and safe because the US isn't engaged in a declared war, but the reality is we've got military personnel all over the globe, and cyber 'wars' are here to stay.
Conflict and violence has escalated in our time, it doesn't have to be a coordinated effort by a government declaring war to affect our every day lives. Just ask airport security.
