Did I understand it well (SPOILER)

I've not read a single review explaining the movie as I did understand it so please tell me if my version of the story sounds right.

Once she meets Orlov, she know her husband is already in danger because O. will use him to make her do what was agreed upon: kill the Russian president. From this moment on, her only goal is to find her husband to protect him. That's why she's going to her apartment but she finds he's been kidnapped. She know she will only get him back if she accomplishes her mission. Once she does (but she take care not to kill anybody), she can find Orlov and his husband but they kill him to find if her real motivation was her husband or the common cause they're supposed yo share. She don't react when he's killed but she's burning for revenge and would like to take down all agents of this organisation, not only the ones located in the rusty boat. She's waiting for Orlov to communicate the rest of the plan before she kills everybody in the boat. She heads towards the Nato agent to see how they will take control over nuclear weapons and kill any agent she can find. Once this agent blow itself up without killing the president, she knows other agents may be around (maybe this is a point I can't clearly explain) and is going after the president. The boss of Salt is then accomplishing its mission which was to create a nuclear war between Iran & US (we learn killing Russian president also caused Russia to be prepared to nuclear war). The rest of the film is more or less obvious.

Is it what you've understood too ?
