So, we're talking about one of the most shameful and damaging mistakes in American history. Yet, the left is pushing to do the same thing in Iraq, despite the fact that catastrophic consequences would surely also follow a U.S. retreat in that country.
But, this isn't just about foreign policy. Look at Lyndon Johnson's "war on poverty," which did nothing to reduce the poverty rate despite the trillions that were spent; however, it did help drive the illegitimacy rate among black Americans from 22 percent in 1960 to 70% in 2005.
You could go on and on with these sort of examples -- rent control, which causes housing shortages, the minimum wage, which costs poor people jobs, the liberal insistence on putting “making nice at the U.N.” above looking out for American interests. That's what happens when you make decisions based on emotion and wanting people to like you, rather than using logic and doing the right thing.
Unlike liberals, conservatives tend to be primarily concerned with pragmatism, not niceties. This is one of the biggest reasons that conservatives have such a healthy respect for the traditions and institutions that have been proven to work over time and such contempt for those that don't, like the United Nations and the federal government.
Does that mean conservatives are opposed to change? No, not at all, but there is a great reluctance to tinker with ideas and concepts that have proven successful time and time again throughout history, because the more they’re changed, the more likely they are not to work.
Moreover, in Thomas Sowell's immortal words, conservatives believe that, "There are no solutions; there are only trade-offs." Because of this, conservatives regularly do something that liberals seldom do: they consider the long-term consequences of their policies.
Sometimes in politics, that's a tough duty. It's always easier to say, "We're going to use someone else's tax money to give you this right now," than it is to say, "We're going to keep government out of your way and let you do this for yourself." But, that's the path conservatives have chosen for themselves. They’re willing to be attacked and called, in some form or fashion, "mean" in order to advocate policies that are good for the country.
In the end, that's what liberalism versus conservatism all comes down to: sappy, feel good emotionalism that sounds appealing, but doesn't work versus doing things the right way, even when it's not easy.
