Recall that an almost complex structure $J$ on a manifold $M^{2n}$ is called *tamed* if there exists a symplectic form $\omega$ on $M^{2n}$ such that $\omega(v,Jv)>0$ for any non-zero tangent vector $v$.

**Question.** Is there an example of an almost complex structure on $\mathbb CP^2$ such that any $C^{\infty}$ small perturbation of $J$ is not tamed?

**Added.** It would be interesting to know if there exists as well a purely *local* obstruction for any small perturbations of $J$ to be tamed. The precise fromulation of the question is given here:    http://mathoverflow.net/questions/263500/almost-complex-structures-on-a-4-ball-that-are-not-tamed
