I planned this out a little more the most.
A few rolls of aluminum foil, a very nice lens assembly, few high grade knives, tool bits, several types of saws and tooth paste.
I would spur an alternative technology development tree so radically different, that /g/ would hate me. (no electricity or computers, but still very advanced things in other ways)
And use that tech for my own political gains, for world peace as I see it.
For example I would introduce body armor that was cheap and could easily stop early guns, (note, modern guns are a completely different matter) thus gun technology would be rendered a curiosity as other weapons prove far more useful in war.
The result of all of these simple technical introductions (given my limited manufacture assets have to be considered) is that I use the current wars to get them to quickly build what I need, then end the war and introduce the new systems to maintain the peace. The following golden age would allow me to live a nice life and bring us as close to world peace as we could responsibly get.
