What is the test for de novo dismissal of a complaint pursuant to Rule 12(b)(6)?

We review de novo the dismissal of a complaint pursuant to Rule 12(b)(6), accepting the factual allegations of the complaint as true. See Forest Park Pictures v. Universal Television Network, Inc., 683 F.3d 424, 429 (2d Cir. 2012). A pro se complaint must be "liberally construe[d] . . . to raise the strongest arguments it suggests." Abbas v. Dixon, 480 F.3d 636, 639 (2d Cir. 2007).
