Most Iraqis remain without a consistent supply of the basics, be it sanitation, clean water, electricity or health services. We are leaving them divided and destitute. Most of Iraqs infrastructure remains structurally ill-equipped, including transportation, utilities, agriculture, commerce, education and health care, among others. American private contractors, funded by the Defense and State departments, had no intention of rebuilding the country, returning the majority of every dollar to the U.S., not to Iraq. Contractors flew in, but money and skills flew out. Little local capacity was built, and as a result, six years after the invasion, the country remains as unstable as ever.Sadly, the same strategy is now being saddled up for Afghanistan.We are again overemphasizing military security instead of political, economic and social security, despite what we know about counterinsurgency campaigns requiring 80 percent political resources and 20 percent military resources. In Afghanistan, much like in Iraq, our ratio is the opposite, with nearly 90 percent of all resources going to military means and less than 10 percent spent on political and economic development.We are again proceeding with a troop surge, despite the recognition that the numbers are more symbolic than strategic. Much like in Iraq, if we really wanted to manage the conflict a choice, mind you, not sustainable militarily or financially we would need to surge with 300,000 to 500,000 troops.We are again choosing airstrikes and drone attacks, while knowing full well how frequently they are accompanied by civilian casualties, thus adding fuel to Afghan ire and creating fodder for further extremist recruitment. Even the military experts involved in Iraq Gen. Paul Eaton and Col. Lawrence Wilkerson, who served Colin Powell as chief of staff are voicing concern about the drone attacks, citing their inefficacy as a counterinsurgency tool and their efficacy in exacerbating radical sentiment.We are again leaving little capacity behind. For every dollar spent on Afghanistan, 75 cents is returning to foreign coffers. As a result, the countrys transportation system, markets and mechanisms for trade, health care system, education system, law enforcement system, and commerce and workforce development remain poorly staffed and underdeveloped. That means the next generation of Afghan lawyers, tradesmen, masons, doctors, engineers, technicians, etc., is not being built. Why? Because the monies spent to develop the countrys infrastructure and skilled labor are leaving with foreign contractors.Afghanistan, then, becomes the Iraq sequel in a resource-sapping sequence of U.S. invasions. It is not only the repeated pattern that is problematic, but also the premise of interventionism. Particularly when our country is in need of these critical resources, the least we could do is spend them efficiently and effectively in Iraq and Afghanistan. But we are not even doing that. We are frittering them away, hurting our country and theirs, too.On Afghanistan, or with the possibility of a repeat performance in Pakistan, we must learn from the not-so-distant history of Iraq. We must rethink our strategy because its yielding little but upset allies, frustrated locals, fodder for extremists and less, not more, security. Change, then, is essential. The courage to do so in Congress, or throughout Washington, remains elusive.Retired Marine Cpl.
