Yes my previous post may look naive but I believe it will happen one day, though not before a lot more suffering and violence, unfortunately. There is nothing like a common enemy to bring people together, be it a crazy group of people, catastrophic natural or man made disasters, or perhaps visitors from another planet!
How stupid the west was to not share its intelligence about ISIS with Russia, what harm could it have done? Recently I heard on the BBC that the Jihadis are now moving around with the general population for safety. Also that they are trying to obtain chemical and nuclear weapons. It is only a matter of time before they or some other group does so.
I do think Britain still has some greatness, but it is on the way out. We have some amazing people serving in the forces and behind the scenes, a pity that the ones in power are mostly self serving idiots and that too many of the upcoming generation are not receiving the sort of education/training to maintain the standards of capability and responsibility that our generation had and passed on to our children. You only have to try calling a govt office, helpline etc to see what the immediate future holds.
Power has always gone in cycles, empires have been and gone, but with globalisation and the Internet, and our total economic interdependence, it may be that over the next 50-100 years instead of a new world power rising up there will be a global levelling out of poverty, wealth and influence as we realise that our security depends on the security of the rest of the world. That may sound like more naivety but many scientists, philosophers and humanitarians are beginning to have faith in the future.
