::::In terms of "balance", the whole thing seems rather silly. There's no need to get into that since the reader can make up his (I'm going to be sexist here, why not) own mind. To one, a 98% reduction is awful because it should be 100% and that makes them angry at Hamas. To another, 98% signifies to them that the whole rocket problem is nothing but Orientialist propaganda. 

 ::::I added the line because I thought that (a)Human Rights Watch is a notable, respected source and (b)Their criticism of Hamas with regards to rockets is notable in this context.
