GDI still possesses a nuclear arsenal stored at key locations around the world (including a large nuke base in the desolate outback of Australia, heavily defended silos in North American Yellow Zones, and installations in other remote areas). GDI leaders long ago made a vow not to ever use nuclear weapons no matter how bad the situation got and kept that vow even as Nod acquired its own nuclear capability. GDI's nukes are few in number but are stored with delivery systems (including ICBMs) and kept at top operational readiness just in case GDI leaders ever change their minds. The most difficult test of GDI nuclear policy came in the early days of TW3 right after the strike on the Philadelphia, but even then it's questionable how effective nukes would have been in stemming the Nod tide given that Nod's forces were highly decentralized and Nod troops were staging operations deep in GDI Blue Zones.? Some view GDI's pledge not to use nukes as a cynical one given that they deployed a new precision weapon of mass destruction - the Ion Cannon - right at the time they made their vow.

GDI仍然擁有核武庫，他們分布在世界各處的關(guān)鍵地點(diǎn)（包括一個澳大利亞荒涼內(nèi)陸的大型核武基地，北美黃區(qū)守衛(wèi)森嚴(yán)的核彈發(fā)射井，以及其他偏遠(yuǎn)地區(qū)的設(shè)施）。GDI領(lǐng)導(dǎo)人很久之前宣誓不管多嚴(yán)重的情況下都不會動用核武器，即使Nod獲得了自己的核能力也堅(jiān)守這一誓言。GDI核武器數(shù)量不多，但是與運(yùn)載系統(tǒng)一起存儲（包括ICBM）并保持最高戰(zhàn)備狀態(tài)以防止GDI領(lǐng)導(dǎo)人改變主意。GDI核政策最艱難的考驗(yàn)在第三次泰礦戰(zhàn)爭早期，費(fèi)城空間站遭到襲擊之后，但因?yàn)镹od部隊(duì)高度分散，且Nod部隊(duì)行動深入藍(lán)區(qū)，核武器能對遏制Nod浪潮造成多大影響也是個問題。一些觀點(diǎn)認(rèn)為GDI不使用核武器的承諾是諷刺的，因?yàn)樗麄儾渴鹆诵滦痛笠?guī)模殺傷性精確武器——離子炮——就在他們做出誓言的同一時間。
