The "implication" is simply your interpretation.

As to the views directly attributed to Galloway, there is considerable evidence (some uncovered by Israeli historians) suggesting that some attacks on synagogues in Arab countries in the 1950s were the work of Zionist provocateurs.

I have never heard of Prison Planet before, but during his just completed US tour, Galloway was ignored by most mainstream US media sources, so he made himself available to anyone willing to interview him. He also appeared on Bill O'Reilly's and Michael Medved's shows. One shouldn't conclude from that that he agrees with their views.
