Well I don't know how likely it is that we go to war with China. However, in this particular case, most LCD technology actually comes from Taiwan. The tension between China and Taiwan could conceivably pull us into a war with China, as we defend Taiwan, or we could just sit back and watch, depending on who is in the white house. In either instance, LCD supply would be disrupted.
I only mentioned drought, because, in an agriculture based economy, a drought is devastating, as you suddenly have a huge reduction in your exports. It doesn't even have to be what you're imagining. Just a wheat crop that's only 60% of last year, could be ugly.
Anyway, we know what the most likely disruption will be, and it's not war, it's currency collapse.
You'd be surprised how easily 40% of the supply of a crop could disappear. P.E.I. produces 1/3 of all potatoes consumed in Canada (this includes virtually all potatoes used by McDonalds, Wendy's and most fast food companies). If a severe problem ever hit P.E.I. it would be devastating, and it's an island a whole factor smaller than the next smallest province and has less than .1% of Canadian land.
As the island only has 1 bridge connecting it to the mainland, and the ferry service is largely only a novelty service any more it would present a serious problem for the country for its food production.
