One of President Reagan’s best-remembered phrases is an exhortation to Mikhail Gorbachev to “tear down this wall“. Two years later in 1989 the wall was indeed torn down and the world celebrated a new era of peace.
So I find I said to read of India’s new walls. The country has aleady built one along its Western border with Pakistan, and is now building another 4000 km one on the Easter border with Bangladesh. In the USA, there is a powerful movement to build a 2000 mile barrier across the border with Mexico. And then of course there is Israel’s wall, which the International Course of Justice has found to be illegal.
If it is a choice between walls and war, my vote is always for a wall. But perhaps that is not the only choice.
