RE: machines of war...
"is it me or are these things becoming entirely pointless... it's becoming more of a who's got a bigger dick situation than actually being worthwhile.."
It is you. Biggest failings of both the first and second world wars were that commanders were trying to fight the last war rather than the current one.
Biggest failure in things like the 6 day war, Suez and particularly VietNam is that commanders were geared up to fight current[1] wars rather than the one the enemy was fighting.
"The merkins fall for this "air superiority" BS"
Air superiority is key in any battle zone. This is basic level "War winning for dummies".
"and it seems a pity that companies like BAE are following suit in trying to hawk this crap..."
BAe / R-R etc are commercial enterprises. Their mandate is making cash - it could be argued that governments shouldn't be spending money on these things but to blame BAe etc. for selling them stuff they ask for is like expecting McDonalds to refuse to sell burgers to fat people.
"There aren't many nations out there who have anywhere like the spending capability to develop better weaponry than what is currently in existence..."
The budget for this was less than 200 million dollars. Very few nations couldn't afford that.
"Can you name a single nation out there who's got anything to cope with something like a Harrier or even a Tornado"
Any of them with a few tens of million dollars to spend. Harriers / Tornados are old tech. It would be like Britain fighting the Battle of Britain with Sopwith Camels - hell they were pretty shit hot back in the day....
"that's likely to declare war on Blighty? (before the inevitable response of the "axis-of-evil" is rolled out, seriously look at their capabilities!)"
Things change quickly. With a dev lifecycle in decades rather than months or years, plus armament times you can't afford to base tomorrow's defence solely on todays political situation. As a quick word to the wise - Libya and Iran have a lot of oil, and Russia has a lot of budget deficiency. 2+2 might not equal 4 just yet but can you afford the gamble?
"The biggest threats to "democratic" nations come from determined people with bombs strapped to themselves or AK-47s - tell me which fucking aerial combat vehicle is going to stop them?"
No, you have described the biggest current threat to individuals. The biggest threat to democratic nations is their electorate - most recent loonies either gained power through mostly democratic means[2] or were assisted by a popular (or populist at least) mandate[3]. The next biggest threat is invasion by a nation gone bad as previously described.
"Seriously, these people have their heads buried far up their arses... This money (if it is the taxpayers) needs to be spent on more useful things"
I'm listening.
" - say better armour/hand-held weapons for poor soldiers deployed in the field,"
UAVs would reduce the need to put bodies in harm's way. Would you rather be shot at in body armour or whoring it up at the local bar whilst the UAVs run your patrol for you?
"or even better spent on addressing the fundamental issues that will cause people to take up arms (though not more bloody focus groups - I fucking hate focus groups!)"
This is a very valid point. However we would be stupid to assume that asking everyone to "just get along" wold sort everything out. There will always be terrorists and there will always be war-mongers. Sad fact, but true.
[1] Like the cold war - basically the same folly as assuming any wars we fight now would only be against untrained jihadists with nothing more offensive than an RPG-7 and a bad attitude.
