First is the deal and its terms. From what is visible, there seems to be little to find fault. The problems will arise only on the issue of perpetuity. Besides, a lot of interpretations need to be done as every thing seems to be too simple for an international agreement of such importance. One could even doubt if this is the full Text in the first place.
The second issue of importance is the way the Congress has treated its important ally on whose support they have survived for over 5 years now. If the Agreement Text was so simple, there was no reason for not showing this to the Left and the Opposition. Congress cannot say that they were barred from this by the IAEA as the Spokesperson of the IAEA has on TV indicated to the contrary yesterday.
