That sir, is like comparing apples to oranges.
The U214 is an attack submarine used for active conventional underwater warfare while what your country is claiming to make is a strategic asset, to be used as a last resort.
Besides, foreign countries especially western ones cannot sell anybody nuclear submarines. If that was not the case, a lot of countries would be armed with imported nuke subs.
To answer the gentleman you had answered:
The U214 deal seems to be on hold for now as far as reports go by. But to say that it has been indefinitely canceled would be wrong as rival European countries would definitely want to tap into this area's market if one country succeeds in convincing a major client here.
