It would be great for the world if the other super powers could take the lead with rogue countries instead of the U.S. playing sheriff all the time. The U.N. Council would enable peace for the whole planet because no one will mess with the super powers combined. Leave the politics out and concentrate on weeding out the dictators. The combined muscle would have the war in Syria, Iran's hate of Jews and Rocket Man assigned to history by now. That is the stage human evolution is at. It is the ONLY solution.
I think it's the nuclear-powered states that's the main rogue states of the world, causing trouble and miseries. It's just statecraft, dominance and general insanity...
For some reason, every political leader want to dominate. Since WW2, and probably long before that, no state believe in another state's rights to have its own sphere of influence. So instead of accepting a world where another pretty powerful state should have its influence and security, each vie to be completely secure... and complete security for one state mean another will not be secure.
I mean, it's not enough we lock our doors, build a fence and put soldiers on it. We must do all that, have weapons cache all over the country
and does not permit neighbours or peer competitor any peace of mind.
Hence, after the collapse of the USSR, NATO and the US move immediately East towards Moscow. Flipping former Soviet satellites to NATO, all until they reach the Balkans, had a proxy war there... and recently the Ukraine, which I think is still going on. Haven't read much about it in the press though.
In Asia Pacific we have China rising. China has always been ambitious and warmongering. It suffered that century of humiliation which saw its colonies lost, its land divvied up among the barbarians.
Since WW2, it's been chained in by the US/West in those 2 or 3 series of "island chains".
Should the US, or any state wanting world domination, permit China its sphere of influence? Probably not.
China reckon it needs it. And given the route Europeans took to "open" China up to the world in the late 1800s, can't really blame it for wanting its own backyard free of barbarians. It helps too that the South/East China seas have crap load of oil and fisheries. That'll come in real handy if/when war breaks and its sea trade routes are blockaded.
Seeing how all these major powers have nukes, they can't, shouldn't, and don't want to, fight each other directly. Hence the proxies.

As to Iran and Israel.
Israel wants to be a regional Hegemon. The only military power in the M.E. capable of defending itself against Israel would be, Iran, Saudi Arabia and possibly Turkey. S.A. has the hardware it's forced to buy from the US but can't much use it anyway - though they're practising it on the Yemeni the past couple years so if ever they to to war with defenceless state, they'll sure be able to kick its azz.
That and both are vassals to Uncle Sam, so they're technically on the same side.
Turkey may have a change of heart last year, hence the coup attempt by (not) the CIA
...
So Iran is the only con-conforming state in the region capable of returning fire if Israel ever decided to fight it for "security reasons" - you know, Arab/Persians always hate Jews, unlike White Christians who always love the Jews.
Anyway, Israel want the US to take Iran out for them. They were hoping Bush Jr. would do it right after Iraq... in fact, I heard some lecture where Israeli's planners was egging Jr. to start with Iran after Afghanistan but have to accept that it's a harder sell to the public (for some reason).
Iraq proves a bit of a nightmare so the plans for Iran was put on hold.
Ever since then, that nutty yahoo have been trying to push for the liberation of Iran by the US. So he got pretty upset when Obama and Kerry follow Big Oil's and Big Business' directives to make peace with Iran.
Hence, having Trump as president is, they think, a dream coming true. Just tell Trump Iran says his hair is too fluffy and who knows, the dude might just "totally destroy" Iran for crimes against humanity or something.

Conclusions... all states are nasty and violent. In liberal democracies, the people do have some influence on foreign policies (if they wanted to)... hence all these "news" and talks of good vs evil, Axis of Evil, going to war for freedom, democracy and liberating brown people we don't particularly like.
So if we blindly believe all the bs, the war machines will grind on and a whole lot of people will die. I mean, Saddam and lil Kim aren't nice dudes, it's horrible to live under those farkers. But a war mean there's no living at all, just death.
Iraq is a worst place now then when it was under Saddam; same with Syria, same with any country getting smashed.
War is not the solution. War is for profits, death, destruction and a statute or an arch of triumph.
