At first I avoided reading student Benjamin Young’s Washington Post op-ed on the influence that the U. S. invasion of Grenada had on North Korean strategic thinking on the grounds that it was yet another reductio ad Reagan argument, popular among progressives. It’s actually a fairly interesting little essay on the actual significance that the tiny Caribbean island of Grenada had for the North Koreans.
I still think that our two wars against Iraq (the Gulf War and our invasion of Iraq in 2003) were probably more influential. You don’t need to hunt very hard to find analyses that Saddam Hussein was just a few months from a workable nuclear weapon when he invaded Kuwait and had he had nuclear weapons the U. S. might well not have responded as it did.
But, yes, I opposed the invasion of Grenada just as I opposed the Gulf War and the invasion of Iraq. It was illegal and immoral. The use of force has consequences that may extend far beyond the scope of the conflict.
