"And I don't think bombers qualify as defensive weapons."
Objectively you are right.
off topic notes:
However, as you propably know just a hop skip and jump away from India lies the USAF strip at Diego Garcia Island.
A nice squadron of potent B52's is staitoned there, with visiting B1s, F117s, B2s and whatever secret aircraft we have in our arsenal stopping by.
Diego Garcia gives us an awesome reach into Asia power projection wise.
So, if India gets a couple Tu-23 backfire bombers kudos to them.
A) It will give the IAF survivability and deep penetration capability against the Chinese. Unlike Taiwan India has the missile and bomber detterent to "middle finger" back the Chinese missiles pointed at her from Tibet. The motive of the aircraft is more likely against the Chinese the Pakistanis.
B) Tu23 will enable the IAF to mobilize the Brahmos supersonic missile deep into the Indian ocean to safeguard against nosy Chinese Crusiers and what not.
The other calculus is Pakistans Block A F16s that we sold them. Anyone knows that would make a good nuke platform. Up until the IAF got the Russian Su30MKI's not much of a match existed.
The other point is the roots of the conflict are more than just Kashmir. As another poster mentioned, it boils down to the British basically.
Historically, the United States(13 colonies) or the middle east (palestine-israel), Ireland-N.Ireland, S.Africa, India-Pakistan the brits went in colonized then tried to divide and conquer them. In America's thanks to Washington and his men the Brits failed to cut us up successfully.
In the other cases the Brits messed everything up. The brits got the pakistanis thinking that all muslims need there own country and hence they did and partioned India.
A blood bathe ensued. The biggest exodus in history happened strictly on religious-political lines. That is where it started, people rightly reject this religious claim...more-ever they reject the legitimacy of the Pakistani state.
And many of those have a good case...there lands were confiscated and they left at the clear present threat that if they did not convert to Islam they would be excuted at there doorstep.
Kashmir is only part of the calculus.
