The rationale is certainly not clear for all these countries acting militarily without invitation in a supposedly autonomous nation. It would seem rather illegal, at best. Machiavelli would understand; as usual, might justifies the use of might. When this comes back to bite America, as such episodes have in the past, those who point out the error will once more be accused of anti-Americanism. Some protested against American action in Vietnam, and we know now it would have been better not done. Some opposed the Iraq invasion, and now we know it was a monumental mistake. Those of us pleading for wisdom now, regarding Syria, do so in the interests of our country, not because we dislike it.
