The authors are correct. The Liberals are doing what Liberals do best. Obfuscation. They did not like the reality that they were hearing from the RCAF and DnD and hated the fact that the Conservatives were spot on with their acquisition cost forecast for the F-35. Of course they couldn't agree going into the last election, so they contrived a capability gap that would allow them to push the F-35 further out of the voter's mind. Even with the interim purchase they're screwing up. If you are going to buy the SH, buy the Block III. To supplement the inevitable F-35A purchase.
