As the United States ramped up warnings of a Russian attack, and as Western allies called for unity against aggression, the leaders of two NATO members bordering Ukraine headed for a gathering in Madrid over the weekend called ¡°Defend Europe.¡±

But instead of tackling the Russian threat to Europe¡¯s eastern frontier, the meeting attended by the prime ministers of Poland and Hungary, Mateusz Morawiecki and Viktor Orban, focused on what the populist leaders cite as their most pressing threats: immigration, demographic decline and the European Union.

Even as the two NATO members rely on the alliance for their security, the pressing in Madrid of issues that have long driven a wedge between them and the United States and the European Union highlighted the extent to which domestic political concerns remain at the forefront of their calculations.
