In 2007, we had the good fortune to be able to make brief visits to both India and Pakistan. The two countries are much closer to each other culturally and socially, than say England and France, so we can only hope that it does not take around 800 years of warfare, as it did in the case of England and France, to realise that warfare and quarrelling is a really dumb way of conducting relations with neighbouring counties and that it is much better to work closely together.
The two countries share many of the same challenges such as: large and expanding populations in crowded cities:

Ajmer, India
Overloaded transportation systems

Village on road from Karachi to Thata in Pakistan
But both countries have a lot of good things going for them, such as incomparable historical sites and architecture

Taj Mahal India

Mosque in Thata, Pakistan, Built by the same Shah Jehan who was
responsible for the Taj Mahal. The 100 domes in the passages
round the central courtyard transmit sound so that the words of
the Imam could be heard all through the building in the days
before microphones and amplification

Tomb of Prince Sultan Ibrahim bin Meerza Muhammad Isa Kahn
Turkham dated 1559. One of the many mausoleums of great princes,
clerics and lesser folk to be found in the Necropolis at Makli
near Thata in Pakistan. .
There are many colourful scenes and experiences to be had

Elephant at Amber, India. This one apparently hates having his
picture taken, The Mahout was shouting a warning to hide the
camera

Pakistani truck encountered on highway in Sind. The colourful
decoration is not just for show but to make sure the vehicle is
highly visible to other road users, especially at night
