English Summary

The article argues that the proposed 'Golden Dome' homeland missile defense project is fiscally unsound and strategically infeasible, citing a projected cost of $1.2 trillion that consumes a massive portion of the defense budget for limited defensive capability. It contends that such systems are unlikely to protect against advanced threats and could dangerously increase the risk of preemptive conflict. Instead of funding this costly infrastructure, policymakers should focus on pragmatic, proven methods to de-escalate tensions and deter the use of nuclear weapons, rather than attempting to 'win' a nuclear war.

中文摘要

本文論證,提議的「金穹」本土導彈防禦計畫在財政上不穩健,且戰略上不可行。文章指出,該計畫預計成本高達一.二兆美元,將消耗防禦預算的大部分,卻只能提供有限的防禦能力。其主張,此類系統難以抵禦先進威脅,反而可能危險地增加發生先發制人衝突的風險。政策制定者不應將資金投入此類成本高昂的基礎設施,而應將重點放在實用且經證實的方法上,以降低緊張局勢和威懾核武使用,而非試圖「贏得」一場核戰。

    The article argues that recent executive overreach and politicization have severely undermined established norms of U.S. civil-military relations. To restore professional standards, the incoming Congress must actively exercise its oversight powers, moving beyond mere criticism to demanding transparency in defense policy and personnel decisions. Key reforms include enforcing meritocratic promotion processes, requiring documented justification for senior officer removals, and preventing the partisan use of the military. These actions are crucial for bolstering public trust and ensuring the military remains a nonpartisan instrument of civilian control.

    The article argues that Donald Trump's unique and prolonged lame-duck period, coupled with domestic political pressures, makes him dangerously prone to international instability. Having exhausted major diplomatic gambits, Trump is expected to channel his energy into high-stakes, unilateral actions, primarily targeting adversaries such as Iran and Cuba. These potential actions—ranging from fresh strikes in the Persian Gulf to attempts at regime change—carry a significant risk of destabilizing regional security and triggering a global economic crisis. Policymakers must anticipate this pivot to high-risk foreign policy to mitigate potential international flare-ups.

    China's economic strategy is characterized by a persistent 'economics of denial,' prioritizing massive state-directed investment in advanced technology over addressing weak domestic consumption. This approach is rooted in a flawed belief that controlling physical capital will automatically generate productivity and wage growth, ignoring the structural imbalance where domestic demand consistently falls short of supply. This overinvestment and underconsumption model is unsustainable. Consequently, Beijing's policies will continue to generate global deflationary pressures and escalating trade friction, necessitating a fundamental pivot toward consumption-led growth for long-term stability.

    The Blue Wave signals significant voter frustration with cost of living and inflation, giving Congress a mandate to prioritize affordability and cost-reduction measures. Economically, the rapid build-out of AI data centers is creating localized stress, driving up skilled labor wages and straining resources, while also facing constraints from power grids and potential local regulatory backlash. Policymakers must manage this 'sequencing issue'—addressing rising costs before full productivity gains from AI can materialize—and anticipate shifts in global data center infrastructure as the market matures.

    The built environment workforce, comprising 15.3 million workers across 95 occupations, is foundational to modern infrastructure and economic stability. While highly paid, the workforce suffers from significant demographic imbalances, being disproportionately white and male, and often lacking clear career progression pathways. To prevent project delays and cost overruns, policy must mandate that capital asset owners treat labor market forecasting as core to project planning. Strategic interventions are required to strengthen career pipelines through robust apprenticeships, improve retention, and actively recruit younger and more diverse workers.
