Britain has traditionally played a significant role in NATO's Northern Flank with 3 Commando Brigade Royal Marines being committed to it's defence, however with the withdrawl of British Forces from Germany, a concentration of Brotain's efforts on the Northern Flank coupled with a Joint French Global Combined Joint Expeditionary Force, British led NATO Allied Rapid Reaction Corps and NATO Very High Readiness Joint Task Force mean forces can increasingly work together and deploy more quickly.
The Swedish and many other countries in Europe are improving their defences and increasing defence spending and this should be welcomed by other allied countries and the US.
