There is so much wrong with this post that I'm not sure where to begin.
1) Nobody has blamed the aircraft as of yet. But in military aviation, there are a thousand factors that can go wrong - design flaw in the aircraft, component failure of any one of the tens of thousands of components and subcomponents, weather conditions, pilot error, sloppy SOP, sabotage, bird hits, short circuit leading to a fire in a critical component, Foreign Object Damage...there are far too many reasons for a plane to crash. It is not always a simple either-blame-the-plane-or-the-pilot situation. These are complex machines, not like a motor car or dishwasher. The best answer to what went wrong is "we don't know", until it can be conclusively established - if that ever happens.
2) The next statement is just plain wrong. The crash rate of the IAF is comparable to that of any other air force, given its size and number of sorties and average age of the fleet. The USAF and USN have crashed several times more aircrafts than the IAF in peacetime, which is not surprising since their size is several times larger and so is the number of flying hours. However, note that the aircrafts of the USAF and USN are usually only half as old as that of the IAF; and yet, they have crashed thousands of F-teens alone, not to mention other jets.
As for pilot training, the IAF usually gives more hours in operational combat jets than other air forces in the region. Check out the average training hours put in by an MKI pilot, for example.
Maybe it is, maybe it's not. We cannot know until investigations are completed.
