Hi,
Pak army has already showed serious commitment and application in the swat valley and waziristan to the surprise of many---.
Over the years the army has been telling the taliban not to provoke them and not to corner them where they have to strike back in force.
The taliban were looking at the un-committed u s army in afghanistan in small numbers---they were clueless as to what the result would be when a 100 thousand strong millitary moves into your area----now theye are learing very fast what a 100k pak troops can do to them and their cause----and still the pak army has been too kind to the ttp.
For that reason---it would be next to impossible for the u s congress to delay the delivery of the F16--52---unless india can pull a rabbit out of the hat---the blk 52's will be landing pretty soon.
