The political intrigue (spoilers galore)

The political intrigue here never made sense to me.

Karras, the politician, had his son kidnapped, originally we're told by some far right group that was opposed to him because he wanted to end the austerity program. The the US embassy man said this wasn't true, Karras was actually a political fraud and was really caught up in some big money debt problem with gangsters and "the rest was classified" which means the US wants Karras to fail for some geopolitical reason.

Then it appears that the embassy man is in league with the kidnappers. During the protest Beckett looks at his hotel room and seems like he's looking for a sniper or some assassin there. Later, Karras is assassinated presumably by a bomb (a muffled explosion and then the embassy man gets a phone call).

The group who kidnapped Karras son also seemed linked to the assassination attempt. Silencing Beckett was part of their operational security.

What's the point of the kidnapping if they're going to assassinate Karras? Kidnapping a national political figure's child surely seems like it would backfire and discredit the other side.

Was there some chance that the kidnapping was a false flag operation, meant to either blame the mafia organization or the far right political group for Karras' assassination which was presumably some other geopolitical plot, presumably involving the US government?

Was there some chance that April, Beckett's girlfriend, was part of the assassination conspiracy? She had used Beckett as cover for renting a room for a sniper and had motivated him to back out of staying there due to the protest and thus free up the room for the sniper?

Was Beckett possibly ALWAYS the fall guy? His girlfriend was a fraud/operative and had duped him into being associated with that hotel room which would then be used by a sniper to assassinate Karras? The big irony being Beckett accidentally kills the woman who involved him in the plot to begin with?

It's hard to see the kidnappers being so eager to kill Beckett in the beginning. He was injured when he saw the kid and had no idea who it was. Why try to kill him at the accident scene? He seems to have some kind of "loose end" status beyond ignorant minor witness, plus they seem to easily be able to ID him later and the embassy guy knows all about him too, which kind of feeds into my Beckett as fall guy and his "girlfriend" an operative.

I'm sure the answer is just "really low effort screenwriting and filmmaking" but the narrative almost seems like its actually a quite complicated bit of intrigue, though we never get any payoff in terms of explanation.
