Well, no.  "Justified true belief" is not knowledge: there exist Gettier
counterexamples.  Essentially, if the truth and the justification are
utterly independent, the result does not count as knowledge.

The crew of a yacht left Boston on 7 November 1918 with the justified false
belief that the Great War was over, based on newspaper reports.  They arrived
in Bermuda on 12 November, by which time the false belief had become
true.  But they had *learned* nothing in the interim, so their belief
was still not knowledge.
