Here the argument presented by the proposition is an attempt to deceive the opposition and the house. The act that the proposition has presented has not been passed by the US government and is highly unlikely to happen in the future as well. The argument is right if the assumption that the deficits are long term. And it is not so. The deficit as a proportion of GDP is still more than manageable and more spending is needed. The only current indication of this is long term interest rates on US treasury bonds and these have been falling.  Secondly from a purely economic viewpoint, the battle between US and Taliban is not entirely negative. Historically military spending can help boost growth as was shown by World War II pulling the US out of the great depression of the 1930s. What nations need when in a recession is more economic activity and the arms industry and the countless other industries a war necessitates makes this war as good as it gets for the economy. Of course there is a danger of the US budget deficit leading to higher long term lending costs but if we look at the date from the last ten years interest rates on US treasury bonds have been falling. Therefore the US can borrow cheaply, has 9 million plus unemployed and companies are not willing to hire as they are already reaping huge profits off labor cost cuts. Economically the war in Afghanistan is good for America.
