I did not climb, and my experience is no longer recent, but I've traveled and spent time in a few places following, and in some cases, during civil wars and or other major, violent disruptions. Assuming your backcountry/wilderness destinations are themselves relatively conflict free, I'd say that the far riskier aspect of travel in such places are in the cities or district capitals of the affected areas, due as much to accidental proximity to some really shady people and groups as to yourself being any kind of a target. Anywhere where there is weak to absent government/security, and an abundance of weapons, grudges, and lack of responsibility, there will be awful things going on in the shadows, and I've seen foreigners get caught in that--some died.
I've also been within a few miles of groups of foreigners and locals (specifically, mine-clearing groups in Cambodia) who were very specifically targeted by the Khmer Rouge. This included Brits and I think a Canadian if memory serves, along with local Cambodians. They were abducted and held for weeks; two captives died, the others were eventually released in some sort of deal.
At that time, areas adjacent to towns like Battambang were considered sure death if you took the train there from Phnom Penh, especially if you were foreign.
Obviously, none of this is the case there now, but I throw out a few of these anecdotes as examples of what could be going on in recent post/current conflict zones.
Other liabilities: unexploded ordnance, which you could all too easily--literally--stumble on in places with heavy overgrowth, as I and a friend did off trail in the northern hills of Laos. Aside: although not dangerous, finding remnants of US ammunition up in the hills was very, very weird.
Characters you might like to avoid: arms dealers/smugglers, drug dealers/smugglers, human traffickers (and, sadly, their traffic), gang members, factionalists, underpaid, undersupported "government" security forces who like to shake down foreigners for their money, passports, or just cigarettes, if you can talk them down to that (as I did once with an AK47 in my face; again, Cambodia during the civil war); bandits (rural travel can sometimes involve random strafing of vehicles, armed convoys, etc.), other various and sundry lowlife predators, etc.
And all of that is to say nothing of the potentially lethal, wild nature of simple traffic and highway driving. I've seen way too many dead people on highways in developing and/or war-torn places, and survived two bus crashes myself, one, with two fatalities (first in China, second in India).
There's also disease and a lack of mitigation, especially as it relates to Malaria (had it...it really sucks...don't get it).
In short, be careful. By all means, go, learn about the culture you're visiting, be respectful, try to make as small a footprint as possible (think of it as cultural LNT), but just be careful and get educated on what you're potentially getting in to.
