The 'America First' ideology presents a strategic challenge for allies like Israel and Ukraine, requiring them to adapt to an inward-looking United States. Israel must prioritize expanding its defense capabilities and strengthening regional ties to reduce dependency on US support. It must also position itself as a stabilizing force against threats like Iran. Ukraine, facing an ongoing conflict with Russia, must demonstrate its strategic value to maintain American support by framing its conflict as a global struggle for democracy and deepening alliances with Europe and NATO. Both nations must enhance their autonomy while reinforcing their roles as indispensable partners to the United States.
