Trump says he discussed nuclear arms limits with Putin, plans to include China

Shift toward US-Russia bilateral engagement on nuclear matters, exclusion of traditional allies from negotiations, and elevation of China as nuclear negotiation partner. Potential weakening of NATO's role in European security architecture and repositioning of US strategic priorities toward great power competition over alliance management.

Resembles Nixon-era détente and Strategic Arms Limitation Talks (SALT), but with added complexity of China's nuclear modernization and absence of multilateral framework involving traditional Western allies.

Potential long-term benefits through reduced geopolitical tensions and defense budget reallocation toward civilian infrastructure; short-term uncertainty may increase volatility in financial markets and energy prices.

Possible renegotiation of arms control treaties (New START), defense budget restructuring, shifts in NATO commitments, and changes to sanctions regimes. May require Congressional approval for treaty modifications and affect international security frameworks.
