Okay, then consider my responses thinking through the situations.
Yes, infiltration and internal division reduces their culpability. If they are compromised, we should not be hampered in our ability to do what is necessary to defend ourselves by their lack of reliability. We must continue to take the least means necessary, and this would be least means, because otherwise we would be paralyzed, and any groups wishing to wage asymmetric warfare need only find a region they can hide out in to act with impunity.
I didn’t say that. We may under certain conditions have a moral case for going into the country to deal with such a problem with or without their help, not on waging war on that country.
See above. Not war with Mexico. Military action, after all other reasonable possibilities are exhausted and warnings are given, to end the cartels’ ability to continue their campaigns of murder and terror. If Mexico resisted or saw this as an act of war, it would be actively harboring and protecting the cartels and thus be entirely complicit and making themselves enemies. As long as the U.S. restrained itself to the least means necessary, As long as its government and innocent civilians were not the target, Mexico could not justly engage in war with the U.S., for mere violation of borders is not sufficient cause for war.
What would they have us do otherwise, do you think? Let the killings continue and the power of the cartels grow unabated, unchallenged, without limit? That would be evil. All that is needed for evil to triumph is for good men to do nothing.
The Holy See is not infallible in these matters, and freely acknowledges that the faithful may disagree, so long as we are honestly seeking to make moral choices and informing our consciences. I disagreed with the Holy See about Iraq, but carefully considered it all. I believe the causes in Iraq and Afghanistan were just, but the means of prosecuting the wars were not always so.
I have. If you’re interested in my position, I have commented on that here:
