Iraq happened more 20 years ago; i.e., half of a working-life and none of "the birds [have] come to roost". If there are lagged effects, they are quite small. If the main drivers of the secular decline in interest rates continue (aging, foreign savings, etc) and the long-talked about recession happen, rates are going to continue on their decades long fall, US capture over developed economies and India is as strong as ever and the 2 decades of US military developments have been boring continuity. Iraq and Afghanistan are largely irrelevant and nothing more than a footnote for the United StatesUS bond yields have been on a steady decline through out the 1980s to now(even with the recent rate hikes, they're still considered historically low), which makes financing military expenditures (and all spending in general) extremely easy. But on the financial, military and geopolitical-goodwill fronts - the birds will have to come home to roost at some point, the question is whether we'll start seeing the evolution of those shifts within the next several years.
