Peter Beinart, writing in The New Republic (I can’t find the article online), says that Bush’s tax cuts are undermining the war on terrorism. They account for 3/8ths of the federal deficit. The deficit has risen to a “politically unsustainable” level, and entitlements aren’t being cut, so defense isn’t getting the money it needs. But why should we assume that it’s the tax-revenue constraint that has to give, and not the entitlement constraint? For that matter, why not try to increase the politically sustainable size of the deficit? Winning the war on terrorism is worth borrowing for–and yes, it’s worth asking our children to pay for.
