In a notable shift from its historical stance, the Spanish government led by the Socialist Workers' Party (PSOE) is revising its approach to defense spending by incorporating climate change initiatives into its military budget.

President Pedro Sánchez, addressing concerns from leftist coalition partners, has emphasized that increased investment in defense should not come at the cost of social welfare.

Instead, he proposes that enhancing security includes measures targeting climate threats.

Sánchez highlighted that while Spain faces a tangible military threat from Russia, the nation is particularly vulnerable to what are termed hybrid attacks.

These involve cyber operations that could lead to terrorism, mass migration, or election interference.

To counter these multifaceted risks, the government is advocating for an expanded approach to national security that integrates cybersecurity, critical infrastructure protection, and civil protection measures in response to climate emergencies, which are especially pronounced in the Mediterranean region.

In line with these assertions, the Minister of Science, Diana Morant, stressed the importance of investing in science, innovation, and technology to achieve greater autonomy and security.

She pointed out that space access is vital for telecommunications and technologies that can warn of climate change phenomena, including extreme weather events.

Experts acknowledge a growing recognition of the need for modernizing military assets.

However, the current focus on defense spending is being broadened to encompass a range of security-related investments.

The Minister of Health, Mónica García, has proposed considering expenditures on medical supplies and vaccine stockpiles as components of national security, preparing the country for potential health crises.

While militarizing traditional defense capabilities, including land vehicles and naval vessels, has been called for by military leaders, the Sánchez administration is looking to redefine what constitutes defense spending.

A government directive has initiated an internal audit aimed at reclassifying various budget items previously excluded from defense calculations.

A report from an independent peace research center suggested that Spain could effectively increase its defense budget by as much as €8 billion by reclassifying certain expenditures, such as those related to the militarized Civil Guard and research and development funding for military manufacturing, which are not currently counted in the official budget.

According to NATO figures, Spain's defense budget for 2024 stands at approximately €19.7 billion, representing only 1.28% of its GDP, marking it as one of the lowest among member states.

In light of geographical vulnerabilities to terrorism from North Africa, particularly the Sahel region, Sánchez has stated the necessity for enhanced protective measures.

While specific links between climate change investments and potential migration induced by environmental factors remain unclear, this strategy reflects evolving priorities.

Germany is concurrently advancing a framework that intertwines defense spending with infrastructure development and climate action, backed by a new debt agreement involving substantial financial commitments.

At the upcoming NATO summit in June, discussions are anticipated to raise the defense spending target to between 3% and 3.5% of GDP, a goal that the Sánchez administration previously aimed to reach by 2029. However, there are no current plans to submit the proposed military budget increase to parliamentary vote.

The government maintains that social agendas remain unaffected by this military expansion, even amidst pressure for increased borrowing from European Commission proposals.

Responses from the left have been mixed; Podemos leader Ione Belarra labeled Sánchez a 'warrior', reflecting concern over militarization, while ERC's Gabriel Rufián called for responsible dialogue beyond mere rhetoric.
