There is everything wrong with the US military.
It is too large and cumbersome and over organised. They have the capability to paralyse an enemy's Tactical E-Maps, his radio communications and his infrastructure. They have weaponry which can obliterate massive tracts of land in seconds and they have carriers which can remain at sea in definitely. Problem is, they are rarely engaged with an enemy who relies on technology, radio communications or economic infrastructure, but who can move his weapons an personnel at will. The only defence against the guerilla is to terrorise his base of support and that sadly is what the US has been reduced to.
As usual the US military cannot learn form their mistakes, because whilst it may be possible to isolate the terrorist form his base of support through fear there is always the chance that many civilian deaths (collateral damage) can actually rally even stronger support for the guerilla. I believe this lesson was learned in Vietnam and again in Somalia, in Iraq and Afghanistan. However it does seems that the US military has finally graduated after learning all those lessons, because they are staying the hell out of it now.
A few years back a huge military exercise was undertaken which cost more than a billion dollars to fund. The scene was set as follows; A rogue national Middle East leader had directed his forces to attack a neighboring nation and the US military machine (Blue Force) was directed to do all in it's power to paralyse and reduce his military capability, capture him and bring him to trial. Sound familiar?
The Red Force command was given to an aging US general who had a commanded in Vietnam. He was renowned for his resource and determination.
Then red force had at it's disposal a huge computer complex which carried detailed information about Military capability, economic infrastructure, communications, social institutions, including political parties and trade unions, plus social and religious grouping an very nation in the world. At any time the US General Staff could use this information to direct their forces at the most favourable point for paralysing communications tactical mapping satellites and target all missile and air bases. They had every advantage at their disposal.
The go code was given for the start of the exercise and by the end of the first day, Blue Force had lost 22 warships including it's carrier and had not landed a single boot on enemy soil. Clearly there was something wrong with the original set up. So they scheduled another day of exercise putting heavy limitations on the commander of Red Force, making it impossible for him to win. The result of this second day was basically the same, heavy loss of ships and no boots on the ground. I believe this went on for a whole week, five days at least.
At the wash-up, the Commander of Rec force was asked how he had managed to prevail when his communications were smashed and he was unable to direct his troops. How did he manage to get planes off the deck? His reply was what could be expected of this exceptional soldier, "We Cheated."
When his communications had been smashed, it made little difference to his chain of a command. He had been expecting all of the actions of Red Force, so communication by light was established for all planes between the control tower and within his squadrons when in the air. After that they were to act on their own initiative and attack where they thought they could do most damage.
His Divisional commanders were instructed not to come to him for guidance, but to act on their own initiative, his Battalion commanders were instructed to do the same, company and troop leaders were similarly instructed. In short everyone was instructed to act on their own initiative and to hell with worrying about mistakes. He said that mistakes were the best learning curve for anyone embarked on a military career and it worked.
When asked how he had managed to sink so many ships, he replied that he was aware of each ship's defence capability and simply saturated it with cruise missiles. One or two were bound to get through and it seems they did.
In short, this general was employing all the lessons he had learned about the fighting methods of the Vietcong. He accepted that he would not have top flight communications and tactical mapping and reduced his military command to the slimmest possible. As the days passed during the exercise his commanders and troops got better and better at scotching the tactics of Blue Force.
In Red force, they had encountered many problems, not least with communicating and assimilating all of the information which the tactical computers could provide. Forces were held back from attacking until the welter of information had bee thoroughly digested and dispositions worked out. That computer was more trouble than it was worth and was actually stifling initiative.
So many billions of dollars have been spent building this massive military complex that it cannot simply be ditched, so it has to run it's operational life, so as not to waste money. Instead of ditching it, the military have been hard at work improving it. Meanwhile The USA has found itself losing ground in every military undertaking is gets involved in. A real big rethink is necessary and the USA staying well out of the troubles is a clear expression of that.
The past 50 years has shown that the mightiest military machine in the world can only achieve partial success in any military campaign and every time it gets involved, it inevitably gets bogged down and finds itself having to answer an angry world for it's bungling and incompetence. This is why it would be impossible to form a coalition of force for use in the Middle East. If it was thought any good would come of it, nations would be signing up in droves, but seeing the carnage and for no gain in Iraq and Afghanistan, they are not so sure.
