''Threat Vector'' is a political thriller novel by Creator/TomClancy and Mark Greaney published on December 4, 2012. The novel features the former CIA agent and president Literature/JackRyan and his son Jack Ryan Jr.

Jack Ryan has only just moved back into the Oval Office when he is faced with a new international threat. An aborted coup in the People's Republic of China has left President Wei Zhen Lin with no choice but to agree with the expansionist policies of General Su Ke Qiang. They have declared the South China Sea a protectorate and are planning an invasion of Taiwan.

The Ryan administration is determined to thwart Chinaís ambitions, but the stakes are dangerously high as a new breed of powerful Chinese anti-ship missile endangers the US Navy's plans to protect the island. Meanwhile, Chinese cyberwarfare experts have launched a devastating attack on American infrastructure. It's a new combat arena, but itís every bit as deadly as any that has gone before.

Jack Ryan, Jr. and his colleagues at the Campus may be just the wild card that his father needs to stack the deck. There's just one problem: someone knows about the off-the-books intelligence agency and threatens to blow their cover sky high.

!!This novel contains examples of:

* TenMinuteRetirement: John Clark decides he's too old and too injured to continue. Then he does.
* AllYourBase: [[spoiler: The Campus comes under direct attack by Center's forces in an attempt to wipe them out.]]
* AntiVillain:
** Qian Kun is a traditional example.
** Fang Gan is a much darker example, though he does make the right call when he has to.
* BigBad: Center is the big bad of the novel.
** BiggerBad: Though General Su is the one, ultimately, who represents the biggest threat to world peace.
* {{Blackmail}}: How Center controls the vast majority of his expansive network of agents.
** This is why Melanie Kraft agrees to help Agent Lipton. [[spoiler: Her father traded secrets to the Palestinians accidentally.]]
* BungledSuicide: [[spoiler: President Wei in the end.]]
* TheCracker: Center's operatives and Center himself.
* CruelAndUnusualDeath: [[spoiler: President Wei's]] death given he seemed one of the nicer figures in the communist party.
* DirtyCommunists: The enemy this time around.
* DrivenToSuicide: President Wei in the beginning [[spoiler: and the end.]]
* EvilCounterpart: Center is considered to be this by the Campus given they're an off-the-books techno-savvy paramilitary organization working for the Chinese government on deniable missions.
* GeneralRipper: General Su intends to secure his legacy forcing the United States to back down. The full lengths of insanity aren't revealed to the President until he causally states he's willing to nuke Tawain in order to make sure they're victorious.
* KarmaHoudini: Valentine Kovalenko is released by the Campus for his role in taking down Center despite his involvement in numerous murders. Arguably, his experience was enough punishment as he can probably never return home.
* HollywoodHacking: Both subverted and played straight. A lot of real-life hacking techniques are incorporated into the book as well as terminology but they're then treated as cyber-gods.
* HopeSpot: Valentine Kovalenko has one when he thinks the Russian Foreign Service is willing to help him against Center. [[spoiler: It's just Center using another of his operatives to manipulate him.]]
* HoneyPot: Center arranges one of these on an outside contractor in order to get some spyware on the Campus (unaware it's anything more than a hedge fund).
* ManipulativeBastard: Center is one of the best in the entire series.
* TheMole: Melanie continues to spy on Jack Ryan Junior for the authorities. [[spoiler: Subverted by the fact they're not the authorities.]]
* NotSoDifferent: [[spoiler: Melanie Kraft hates her father because he was taken advantage by a HoneyPot operation and traded valuable secrets to the enemy. Melanie ends up accidentally betraying the Campus to the Chinese.]] This allows her to reconcile with him in the end.
* OnlySaneMan: President Wei is this to the entire People's Republic of China. It's very likely they would have benefited immensely if they just followed his advice the entire way through.
* PeoplesRepublicOfTyranny: How 21st century China is portrayed in the book.
* RedChina: The enemies for the book in all their communist mustache-twirling glory.
* ShameIfSomethingHappened: President Wei says this to President Ryan [[spoiler: about General Su. Ryan gets the hint and has him assassinated.]]
* ShipSinking: [[spoiler: Melanie and Jack breakup due to the lying done in their relationship.]]
* TheSociopath: Center is explicitly described as this in the text.
* YellowPeril: Avoided in the book, albeit just barely, by the fact numerous Chinese characters exist to fight the communist menace.
