I agreee Steve5 - and I do wonder about the thinking of the government who, after all, do not have to live (and die!) with the decisions they make.
I recall the reluctance of the Tory government to engage Argentina over the Falklands, because with the exception of Thatcher and one minister, everyone around that table had been directly involved in a war, and knew what military conflict is really about.
Now, it's an abstract concept, and pushed by people who have a versted interest in it - generals and so forth, whose raison d'etre is to fight other armies.
It's time to be civilised, and try diplomacy first and hardest, threats last and least, and military invasion not at all.
