Yes. It would not cause massive starvation -- for world food production has increased inexorably every decade, even through the oil shocks and embargoes of the 1970s, utterly disproving your completely unsupported fantasies (rather, the corrupt governments of Africa would continue to cause massive starvation of their own populations, exactly as they are doing now).
The great rule of conduct for us, in regard to foreign nations, is, in extending our commercial relations, to have with them as little political connection as possible. So far as we have already formed engagements, let them be fulfilled with perfect good faith. Here let us stop. -- President George Washington, Farewell Address
Washington regarded your kind of chicken-little war-mongering as being the bleatings of Dupes and Tools.
I do as well.
Once we have killed the enemies that fools like yourself have created for us (by your treasonous, moral-cowardice policy of sacrificing your own fellow-citizen's blood for "cheap oil"), we would be well advised to ignore all the Interventionist "Cultural Jihad"s as the always-Wrong Dupes that you are, and return to Mr. Washington's sage advice.
