Liberals can be disarming. In fact, they are for disarming anybody who can be disarmed, whether domestically or internationally.
Unfortunately, the people who are the easiest to disarm are the ones who are the most peaceful -- and disarming them makes them vulnerable to those who are the least peaceful.
We are currently getting a painful demonstration of that in Ukraine. When Ukraine became an independent nation, it gave up all the nuclear missiles that were on its territory from the days when it had been part of the Soviet Union.
At that time, Ukraine had the third largest arsenal of nuclear weapons in the world. Do you think Putin would have attacked Ukraine if it still had those nuclear weapons? Or do you think it is just a coincidence that nations with nuclear weapons don't get invaded?
Among those who urged Ukraine to reduce even its conventional, non-nuclear weapons as well, was a new United States Senator named Barack Obama. He was all for disarmament then, and apparently even now as President of the United States. He has refused Ukraine's request for weapons with which to defend itself.
