Cost are basically what it all comes down to.
The ludicrous estimates of both LM, the Dutch and canadian government are all directly contradicted long time ago by the Norwegian accounting office who did a rough calculation as to how much the total 30 years costs would be for 52 F35A's which lead norway's RAdm Arne Røksund to say that they where looking at 40 billion$ for 52 planes , or 800 million per copy.
The Dutch publically used the LM numbers ,claiming that they could therefor afford 86 copies, it was revealed as early as 2010 by a reputable news program , KRO reporter, that the government was deceiving the parliament and already knew back in 2009 ,and probably even much earlier , that the whole JSF project was going to be a lot more expensive , so much so that they where talking about reducing to 50+ copies and later on even as low as 38.

Even the USAF already said publically that the numbers used by LM and Canada are far from realistic.
Anybody who cannot come to terms with these realities should reflect on their abilities to distinct between fiction and reality.
