Bullets and bombs killed nearly three-quarters of a million people in wars between 2021 and 2024. Many more died from the indirect effects of conflict, such as hunger and disease. Combat deaths in the past four years have been the highest since the end of the cold war. And for what purpose? Not even the leaders who started recent wars can be pleased with the results. Russia’s invasion of Ukraine has become a humiliating quagmire for Vladimir Putin. President Donald Trump’s war on Iran has gone badly awry. These two wars of choice exemplify two new battlefield truths. Technology has made it harder for any army to advance on the ground. It has also made it easier for weaker powers, when attacked by stronger ones, to cause havoc.

In a valedictory essay this week, The Economist’s defence editor reflects on how war has changed over the past decade and how it might evolve in the future. The first big shift is that soldiers are more exposed on the battlefield. Sensors and satellites can see them; small, cheap drones can kill them. Armies have to work harder than before to hide, move and survive. Ukraine’s expanding front-line “kill zone”, where soldiers move in small groups and ground robots evacuate casualties and deliver supplies, embodies this shift.

Technology quickly spreads. Israeli soldiers in Lebanon now face the same kind of drones that were pioneered in Ukraine. Iranian missiles are far more accurate than the Iraqi Scuds fired during the first Gulf war. Were China to attempt to invade Taiwan, its landing forces would be met with a blizzard of drones. Air superiority is now harder to achieve and buys soldiers less protection than before, thanks to the new drone-saturated layer of airspace.

Some experts draw the lesson that manoeuvre—attacking an enemy’s soft spots through shock and rapid movement—is no longer possible. But war is a Darwinian environment, driving constant adaptation, and the battlefield is never frozen for long….

Read it all.

In future wars involving long-range drones and missiles, Western civilians will not enjoy the sanctuary they have come to take for granted. The laws and technology of armed conflict have changed https://t.co/MaIcvygB4S

Draw the souls of thy people into thy love, O God; that, like thy servant Mechthild, we may yearn to be fully thine, for thou dost know us better than we can know ourselves; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Ghost, one God now and for ever. Amen.

O Lord, from whom all good things come:
grant to us your humble servants,
that by your holy inspiration
we may think those things that are good,
and by your merciful guiding may perform the same;
through our Lord Jesus Christ,
who is alive and reigns with you,
in the unity of the Holy Spirit,
one God, now and for ever.
Amen.

Another parable he put before them, saying, “The kingdom of heaven is like a grain of mustard seed which a man took and sowed in his field; it is the smallest of all seeds, but when it has grown it is the greatest of shrubs and becomes a tree, so that the birds of the air come and make nests in its branches.”

He told them another parable. “The kingdom of heaven is like leaven which a woman took and hid in three measures of flour, till it was all leavened.”

All this Jesus said to the crowds in parables; indeed he said nothing to them without a parable. This was to fulfil what was spoken by the prophet:

“I will open my mouth in parables,
I will utter what has been hidden since the foundation of the world.”

–Matthew 13:31-35
