England seem to forget that without the help of USA, They are completely helpless, they may start the war but i doubt they will have the power and weapons to end it with help, Even the USA needed help in Afghanistan.
Yes.. decades of cost cutting measures have left the British Armed Forces as a toothless organization incapable of waging a war against well equipped armies. Without the USAF, they will find it difficult.
And who exactly would start war with United Kingdom first? Ze Germans?
Much like North Korea or Unted States, UK has massive deterrent in form of sea and nuclear arsenal. So there are only two options for conflict.
1. Civil war.
2. Starting more wars on foreign soil.
I belive the second option is undesirable
the former doesnt really call for a strong army, since its weapons would end up on both sides of th war. Like in Syria or Yugo.
