WIND seems certain (wind keeps your kite aloft, you wind up the string to reel it back in).
Kites can be shaped like a TRIANGLE or BAT. Or, more rarely, ROUND. I think Lewwyn lives in China, though, which would make round kites more common?
A kite is a kind of bird, I believe. Do they eat FISH?
Yeah, the missing word cant be BOOM otherwise a (2) would have sufficed. and This clue isnt doubling up on the CYBERWARFARE otherwise it would just say (3) id suppose.
Id go with FISH for Phishing as the "+1" with BAT-TOWER being a given.

In this game that's going to help us because he's going to go to the negotiating table with twitchy eyes and slightly too wide a grin and terrify the neighbors into favorable border agreements, one-sided tech deals and staggered NAPs."
