Stretched military in Iraq.

I am seeing constant reference to how our military is ‘stretched’ almost to the breaking point. This would lead me to believe that we are losing the war. This implies that our military is barely able to handle the war and our commitments. This would seem to indicate that we would be unable to escalate the war any further in order to win it. The side that can keep escalating wins wars. If our capacity is reached, we would be unable to match any further escalating and would by default, lose the war. The logical step is to lower the pressure on our military and reduce our commitments. We would then be able to ‘rebuild’ our military.
During wartime, the armed forces are constantly being stretched. The system is designed to function in this type of environment. The idea in warfare is to push so hard that the enemy cannot push back hard enough to beat you. If the two sides are anywhere near equal in strength and abilities, then the war must last long enough for one of them to get so tired that they either surrender or quit. Are we really that tired? Is our enemy really that strong?
Even if you do not agree that we should have our army in Iraq, you have to admit, this is a war. Standard guerrilla warfare. Compared to other wars in our history, this one is small. Our military has handled far worst disasters than what we are seeing in Iraq. We have lost more than 4000 men in a day. We have sustained far greater losses and loss of equipment that had gone on for years. And we are at the end of our tether?
No. We can sustain a much greater effort if we wish to. The problem is not how our military is ‘stretched’ to the breaking point. The problem is that we believe that the war is not worth it. The war is not worth the losses already sustained. Any additional effort to win is wasted effort and pointless. In this case, we really are tired of the war. Psychologically tired, not physically. I do not buy the hypothesis that our armed forces are ‘stretched’ to the limit. As with all guerrilla wars, we have a stronger military, better training, better weapons, and greater numbers. (Combatants) We may not win the war, but it will not be because our enemy is militarily stronger than we are.
