President Trump boasted about the military in his State of the Union address Wednesday night. Trump is right that the military has received significant investments during his tenure. But recent events also reveal where there are vulnerabilities. Iran’s missile attack against bases in Iraq last month wreaked havoc, although mercifully not resulting in the deaths of Americans. But the attacks showcased the formidability of the Iranian missile force and provided a glimpse of what a missile attack could do to the United States homeland if we are insufficiently defended.
