IIRC, the Trudeau marriage was in early March, Margaret moved in with Pierre, and the press went bonkers stalking the young Margaret as the new FLOC married to an older Pierre.
Justin was born in late December.
Take a look at a Pierre yearbook photo, and an equivalent Fidel photo of about the same age.
The two share a lot of similar features, so yes, it's easy to make that jump.
I think that photo of Justin with Fidel was when Justin was two.
During their honeymoon in the Caribbean, they disappeared from sight IIRC for 8 days. It was theorized that the elder Trudeau met with Castro during that time.
It is also theorized that Castro boned that whore at or around the same time.
And 9 months later this little bitch was excreted.
