• President Trump's lack of engagement with the Quad alliance raises concerns among India, Japan, and Australia.
• The Quad's future hinges on Trump's personal engagement with the grouping.
• A weakened alliance could stall joint efforts to counter China's strength in the Indo-Pacific.

The Quad alliance's effectiveness may be compromised by Trump's disinterest, which could embolden China's expansion in the region and undermine the US's strategic partnerships. This development suggests that the US's commitment to the Indo-Pacific region may be wavering, which could have significant implications for regional security and stability.
