[X] for the President. It's painful, but can China even
afford a way? The government has a responsibility not to overreact, and going to war in Afghanistan, right on the border of your (sometimes) ally and trade partner may well lead to a united front between the two. India isn't the only one with outstanding territorial claims against the government, after all.
Pissing against the tide here, but it needs to be done. First, let us dispense with the emotional arguments. Yes, they hit us and there is a natural desire to want to hit back. However, instinctive reactions do not good policy make. In fact, a key terrorist strategy is inducing the target to overreact. Afghanistan has been a complete mess for the United States in real life. Almost seventeen years after the invasion the Taliban is again ascendant and is currently fighting for control of Afghanistan's seventh largest city.
The pro-war camp is too fast to dismiss the challenges we face. First, simply throwing money at infrastructure projects will not magically heal the nation. The United States has spent massive amounts of money on Afghanistan and look where we are today. For instance, according to a
2016 Washington Post article, I found the US spent $3 billion on roads but 85% were not properly maintained. Second, the entrenched culture of corruption has no easy fix. I don't know of any easy way for an invading foreign power to impose cultural change without excessive violence. Third, as long as the militants have bases in Pakistan we will never be able to truly defeat them. They will always have a place to recover, rearm and train new recruits. To those suggesting that we simply topple the government of Pakistan, I suggest you think of the implications of what you are suggesting. We would simply be creating a whole second insurgency against the puppet regime, assuming that the regime change operation was even successful. Furthermore, Afghanistan cannot replace Pakistan as an ally. Pakistan has a population of 193 million, Afganistan 35. Pakistan a GDP 283 billion, Afghanistan 19 (and that is only after heavy investment). Most importantly only Pakistan has the military and nuclear program to counterbalance India.
Edit: I would prefer we abstain due to the political issues involved, but that is predicated on the assumption that if we abstain there will be no war.
