"Chiến tranh hiện đại không thể thắng chiến tranh du kích."
Translation:Modern warfare cannot win guerrilla warfare.
The use of "win" in this and a previous sentence sounds very unnatural in English. Instead of "win", I would use "beat", "defeat" or "win against".
We're in the process of replacing "win" with an appropriate verb. Thanks for pointing that out.
"win against" is much better in this case, if that helps. It must be a tough process, since this comment was posted two years ago.
