@Cruiser Most rulers throughout history have relied on advisors as it is humanly impossible to excel in all areas; ruling something even the size of a large city requires a diversity of skill that few have.
That said, most voters are more concerned with domestic policy, and as a four-term mayor of a modest city, he has a bit more experience with the executive end of domestic policy that those whose political careers are either purely in Legislative end or non-existent. The same could also be said of the governors running for the Republican nomination if they actually had any successes during their terms. But if you’re trying to get votes, it does make sense to play to one’s strengths and to focus on the issues that are of greater concern to a larger number of voters.
When asked about Israel, he has been quoted as saying, ”“This is a very depressing and difficult issue. This has gone on for 60 bloody years. If you’re asking me, do I have a magical solution? I don’t. And you know what, I doubt very much that you do.”. Regarding ISIS, he feels that the US should oppose them, but should do so as part of a multinational effort rather than leading the fight; phrases like ”...a barbaric organization…” and ”...a growing threat…” tell ME that he is pretty much opposed to them regardless of what right-wingers say about him (and any other person who opposes bombing the entire Middle East just on general principle) being a Muslim sympathizer.
Furthermore, I’d say that between the sixteen years he was in the US House of Representatives and his time in the US Senate, he has dealt with enough foreign policy issues at the Federal level that, combined with his executive experience, he is no less well-versed in foreign policy than most of the other candidates, and far better than a few.
The picture you posted sums up Trump’s foreign policy perfectly though. I predict that his first executive action would be airstrikes in the Middle East, and that the only thing that would save Mexico from getting nuked as well is that the fallout would drift into the southern US.
