The changes to your GPR are updated based on the following rules:
Note that each increase is considered separately, e.g. if the first two conditions are fulfilled for a given round, your GPR increases by two. Once the GPR table has been updated and any sanctions have been imposed, the next round begins with negotiations about NW Counts. The specific rules for changing your GPR are not known to any other country, but you are free to share part or all of them with other countries during the diplomacy stage.
As the U.S., your nuclear arsenal is the largest and you have a definite interest in reducing global weapons stockpiles. You recently signed the New START treaty with Russia, an extension of your Cold War truce to simultaneously decrease your massive nuclear stockpiles. In 2005, you announced the U.S.-Indian Civil Nuclear Cooperation Initiative, agreeing to provide nuclear energy and weapons technology in exchange for India improving its security and nonproliferation efforts. Nominally, you are also an ally of Pakistan and have offered military and economic aid, and you strongly support peaceful dialogue between India and Pakistan; however, the relationship has been strained recently. Lastly, China is a rising regional hegemon that could threaten your influence in the Eastern hemisphere.
Look over the rules carefully and think about your goals before beginning talks. While negotiating for global weapons reductions, strive to maintain your status as a geopolitical superpower. You also have an interest in keeping Pakistan’s stockpile in check. With the largest NW Count at the start, consider your probability of being attacked in the first round if global stockpiles are not reduced; this is further incentive for global reduction. Your goals need to be accomplished through both negotiation and careful managing of your weapons stockpile. Remember when negotiating that you can try to get a third party to put pressure on a target country.
