1. The debt
At the start of the war, the Bush administration predicted that it would cost around $50-60 billion in total. They were wrong by more than a factor of ten, sending the U.S.’ debt soaring, a condition that has yet to be rectified. According to a recent study, the war is set to have cost the U.S $2.2 trillion, though that number may reach up to $4 trillion thanks to interest payments on the loans taken out to finance the conflict. Of that staggering amount, at least $10 billion of it was completely wasted in rebuilding efforts.
2. The physical and psychological strain on U.S. troops.
The soldiers charged with fighting the war were stretched to their limits, put through multiple tours, with increasing length of time overseas as the war stretched on and shrinking downtime in between each. All-told, over 4,000 U.S. troops died during the country’s time in Iraq, with another 31,000 wounded in action. In the aftermath, the cost of providing medical care to veterans has doubled, adding to the difficulties faced by those who served. Up to 35 percent of Iraq War veterans will suffer from PTSD according to a 2009 study, while the suicide rate among veterans has jumped to 22 per day.
3. The forgotten war in Afghanistan.
Even worse, the war in Iraq caused the U.S. to take its eye off the ball in Afghanistan. Rather than following through, the Bush administration allowed the country to stagnate, prompting a Taliban resurgence beginning in 2004. As the West focused almost exclusively on Iraq, Taliban fighters imported tactics seen in Iraq to great effect, keeping the Afghan government weak and U.S.-led NATO forces on their heels. The result: the United States is still attempting to tamp down on Taliban momentum today.
4. The opportunity costs.
Aside from missed opportunities in Afghanistan, the Iraq War-effort was all-consuming, pulling resources from all other areas of U.S. defense policy. Relationships with key allies were allowed to grow stale and U.S. prestige around the world plummeted. Fighting in Iraq was realized to be a diversion from combating al Qaeda, drawing funding that could have gone towards a litany of other efforts to effectively counter terrorism.
5. The strengthening of Iran and al Qaeda.
The power vacuum left after the fall of Saddam and the lack of adequate U.S. forces left room for U.S. adversaries to fill the void. Counter to what some still believe, Al Qaeda had no presence in Iraq prior to 2003. Instead, it was only in the post-Saddam climate that they gained a foothold in the form of Al Qaeda in Iraq. The group continues to carry out attacks against civilians to this day, keeping the Iraqi government on edge.
In the end, it was not the United States that gained the most strategically from invading Iraq, but the Shiite-dominated Islamic Republic of Iran. In removing Saddam Hussein’s predominantly Sunni regime from power, the U.S. opened the door to a greater Iranian influence in the region. That influence has been seen playing out counter to U.S. interests in situations such as allowing Iranian planes bearing weapons for Syria to cross Iraqi airspace.
“The end of former Iraq President Saddam Hussein’s brutal regime represents a consider- able global good, and a nascent democratic Iraqi republic partnered with the United States could potentially yield benefits in the future,” CAP’s Matt Duss writes in the Iraq War Ledger, A Look at the War’s Human, Financial, and Strategic Costs, “But when weighing those possible benefits against the costs of the Iraq intervention, there is simply no conceivable calculus by which Operation Iraqi Freedom can be judged to have been a successful or worthwhile policy. The war was intended to show the extent of America’s power. It succeeded only in showing its limits.”
