I'm not quite as ethically libertarian as most people here on foreign policy, though it is the issue I am most open minded on, and will keep developing on it through the years. Therefore I don't have the "man this pisses me off so much that this is a dealbreaker" reaction to Cruz's foreign policy. I am however, very fiscally conservative on the military, and believe that we can save more lives in the long term by preventing ourselves from going deep into debt today from military spending. I also see a lot of danger in things like toppling Assad, and one thing Cruz is consistent on is warning about the dangers of toppling dictators & leaving power vacuums. I still see no evidence that Trump or Rubio would be better than Cruz as President. Rubio is the most hawkish out of all the Republicans. On paper, Trump is supposed to be one of the least hawkish, but in the debate today he said he wants to "make the military stronger than ever"; Trump panders to pro-war Republicans more than anyone else by talking big on the military, while at the same time trying to be fiscally conservative. I don't trust Trump at all, and he doesn't understand freedom issues.
I think one of the reasons I perceive Cruz differently than a lot of people here is because I'm a paleocon, whereas a lot of you are pure Libertarians. You guys compromise from farther "left" to support Rand Paul, and so going from Rand to Cruz is two leaps for you guys, rather than one leap for me. I am pretty socially conservative, and agree with Rand on almost everything, though he is a bit too marijuana friendly for my traditional values, and I'm a little flexible on foreign policy for humanitarian reasons. Another difference between me and much of yourselves is that I hate Socialism much more than half-establishment foreign policy. This is because I see Socialism as a long-term threat to permanent freedom loss, and our youth may fall for it as they get sucked further and further into the follies of instant gratification. Note: Obviously none of the Republicans are Socialists, so bringing this up may seem irrelevant, but it's to further give you an idea of my mentality as a voter; it shows why I can't stand someone who tries to make being more left on the economy popular for conservatives, like Trump and Kasich do. An aggressive foreign policy however, is nowhere near the same threat to permanent freedom loss as Socialism, as there will always be those in the U.S. that want to pull out of most foreign situations (I guess we can thank the liberals for that). So the idea of non-internationalism is extremely hard to kill in this country, as opposed to conservative economics; left wing economics are a threat to kill not just conservative economics, but the passion for them; a new generation that is born into a Socialist country which only has a healthy national debt due to less military spending will not be able to realize the moral follies of the rules they live under. The biggest long term threat about an Establishment-aggressive foreign policy, like Rubio's, is that we'd get stuck in a war that we can't pull out of, and the national debt would skyrocket (like it did under George W. Bush). Ted Cruz on the other hand, does not want a war that we are helplessly chained to for a long time (e.g. a ground war). He illustrated this well in today's debate when he said "We hit them with force...and then we get the heck out." (forget exact quote).
