Bangladesh, a country which got it's independence from Pakistan only because of India's help is such a mean and ungrateful nation. Well since now Bangladesh is becoming such a problem for India, here are a few suggestions to improve upon. 1. Increase patrolling by Indian Army along Bangladesh border. 2. Use of technology to detect infiltrators. 3. Monitory gifts to individuals who provide information abt ppl from Pak/Bangladesh who are illegally stayin or have outlived their visas. 4. A thorough background/referee check while providing employment to stop Bangladeshis from getting employment in India.(Even for domestic help jobs). 5. Capital punishment to illegal immigrants. 6. General awareness among the masses will also help a lot. I think, this should deliver gud results.
