Don't remind me of the 70's. I was sat in Bramhall oil terminal then orchestrating the fuel "allocation" to forecourts (We were not allowed to call it rationing), watching the lights go off 3 days a week and inflation inch towards 22%.
How times change.
In those days we were punished by OPEC for aligning ourselves with Israel in the Yom Kippur War. Now Israel is inching towards Moscow, the overlords of the skies above Syria and therefore Hammas, Moscow is realigning itself in its relationship with Iran, which now feels itself able to be more than friendly to US and UK overtures.
All above my head. I became in later life a boring old historian taking lessons from not stopping Hitler with the Sudetenland (now read Donbas), Anschluss (Now read Crimea) and the rest of Czechoslovakia (now read Ukraine). If we waver now, in our search for a solution without pain, then we are simply putting off the inevitability of WW3.
Our only concern should not be the ability of Nato to prevail in a conventional conflict but whether there are enough Russian hands around to keep an isolated, and what looks to be an increasingly unstable, Presidential finger off the button.
